    Poor Idle

    It is mentioned that the idle control is turning on at 1500 and taking 24 degrees out, can I make it take less out and so the revs don't drop too quick and stall?

    Poor Idle

    Totally forgot about the firmware! Okay so I updated it and then did two logs. One with the ethrottle as it has always been, and one with the ethrottle set to 0. Setting the ethrottle to 0 doesn't do the idle any favours, it makes it really bad. With log 1, the idle is good but it still tries to stall when I give the throttle a blip Log 2, this is worse than log 1. Doesn't idle well. Can't stress how much I appreciate the help guys! Firmware update - log 1.llg firmware update - log 2 ethrottle set to 0.llg map for log 1.pclr map for log 2.pclr

    Poor Idle

    Okay, so I made the changes in two stages. Firstly I changed the timing and ran the car, then I kept the timing changes and made the PID setting changes and ran the car again. From just the timing changes, I thought this had fixed the car, the idle was very good. But then it stalled again, the only time it stalled is when the rev's hanged for a few seconds, then just dropped. Refer to log 1 attached Once I made the PID changes, the idle was terrible. Bouncing up and down nonstop even when I didn't touch the throttle. I have attached log 2 and the map showing the changes I made, perhaps I made the changes incorrectly? Really appreciate the help guys. 1.llg 2.llg allchangesmadeidlestillnotgood.pclr

    Poor Idle

    Thank you for the reply cj. I will try your suggestions tonight. I must say I'm rather disappointed that I've taken the car to two different dyno tuners here in Perth, one that specialised with link ecu's and the car has never run great (aside from onboost). I will play around with what you suggested, however does link offer any remote tuning services (obviously don't mind paying), if I can't manage to get this right myself?

    Poor Idle

    Okay I literally only had 2 minutes with the car tonight, and I made the changes you suggested, however I haven't had time to update the firmware. I will do that tomorrow. But from the changes made, I couldn't select the speed lockout as you mentioned the firmware is old, but I could change the other settings. The idle was much improved, however if I touched the throttle the engine would rev (seemed way more responsive), it would then hold the revs for a matter of seconds, and then drop all the way down and try to stall. The first couple of times it did stall but from the log I've attached it didn't quite stall. A step in the right direction but something still isn't right. I noticed on my AFR that it went very lean when it almost stalled. changesmade.llg

    Poor Idle

    Another question with this. Say I coast above 2kph (If I'm lazy and put the car into neutral rather than down shifting before coming to a stop) will the 2kph lock out impact this negatively at all?

    Thank you very much for your help. I will update this when I next get time (most likely tomorrow) and report back. Thanks

    Overrun Timing Control

    Made the changes and I've got the desired effect! Sounds great. Thanks for the help. Throttle response seems to be a little worse but I'm happy to pay that price as it's a very laggy car anyway (no boost until 3.5k) Two quick questions: Q1. have I taken too much timing out at high rpm? I've only tried it from 3000rpm down to 2000rpm and it sounds great Q2. some of the pops are a little loud like a backfire, if I take some fuel out I'm hoping that will fix it a little. Any suggestions on how much I would lower the fuel values, and what region (difference between MGP vs MAP as I understand will be the atmos pressure?) Thanks

    Overrun Timing Control

    Hi guys, Another thread regarding retarding timing on overrun. I have a car that has been professionally tuned and is running great, however I would like to have a little play around with getting the "rally car" pops and crackles on overrun. The car is very rarely street driven (very rarely driven), and I understand the accelerated wear on the exhaust + cat. The car currently has the overrun fuel cut turned off (does induce a little bucking around 1500 rpm in first but I just put the car into neutral before coming to a stop to avoid this). Having the fuel on overrun made no difference to the exhaust note so I'm hoping if I retard the timing that will have the desired affect. I'm just wondering the best way to do this. If I have a big difference in timing from 0% throttle (eg -10deg) to the next increment in the ecu, say 5% throttle (eg 10deg), will that have any undesired affects? I thought I would ask here before I play around. Cheers

    Overrun Timing Control

    Thanks Simon. The 4d table sounds a little complex for my knowledge so I might just take your advice regarding using this table. I guess I just take some logs to see what the MAP is at light throttle vs 0 throttle so I know what cells to adjust in the table. Would it be disastrous if I had -ve timing whilst I am light throttle? Just incase I get it wrong at first.

    Overrun Timing Control

    I also note when my car was tuned, the timing is dependent upon MAP, not throttle %. If I change the axis and alter the throttle position settings, I believe that would mess up the timing for all other conditions? Seems I may not be able to do this without a professional retuning the timing? I'm hoping I'm wrong...

    Overrun Timing Control

    Thank you Adam. Could you advise a reasonable starting point, and a figure you wouldn't want to go past? Or is this fairly safe from an engine point of view. Cheers!

    Poor idle

    Hi guys, I got my car tuned professionally and I will likely be taking it back to get some touch ups unless there someone here identifies a simple fix. The car idles quite poorly, it constantly goes up and down from 900-1300rpm. Also on light throttle it struggles to rev (this is especially bad when cold on e85). I've attached a log. One thing to note, timing is all over the place AND something that I feel could be the culprit, the VVT is constantly turning on and off which seems to be causing this problem. The log is from a cold start (20 degrees) on about e50. If it's a more complex issue of fueling I will simply take it back to the tuner but hoping to save some time and $$. Thanks Log 2017-09-26 9;22;37 pm.llg ecu26092017.pclr I just unplugged the VVT and the car idles really badly, almost stalls. So I really think this has something to do with it. Surely VVT shouldn't be turning on and off at idle?

    Poor idle

    You sir are a genius. I tried all of the changes you recommended CJ but unfortunately they didn't work, feeling defeated I put everything back to standard and made the changes to the injectors as Adamw recommended and the idle is near perfect! Throttle response is so much better as well, before it was terrible but now it's great and the car drives so much better. I can't believe I have driven with the car the way I had it for over a year. As you can see from the log the timing is still very low but the car idles much better. Any suggestions of other things to change? I am very happy with how the car idles now, but if anyone notices any glaring problems I'm all ears. updated injectors.llg

    Poor idle

    The difference in values could be due to the fact that I use a 3bar FPR and the table is for 4bar? I don't think I will play with these settings as it's probably best left for someone who knows what they are doing and I certainly do not haha. At least I can give the table to the tuner. I'm not sure why there is a LG1 in the ecu as my innovate wideband O2 is not wired into the ECU at all and was never intended to be. The ecu has its separate O2 sensor which is the factory sensor. It's a shame that ECU isn't picking up this sensor, I will investigate that tonight. The ECU is a plug in ecu, no additional wiring was done apart from a switch to change between high boost and low boost, the flex fuel sensor and the AIT sensor. All was done by the tuner. Given some cars which use this engine only have narrowband O2 sensors, maybe the ECU is setup to accommodate all models of the 20v 1.8t? I wonder if it is picking up the O2 sensor somewhere but just doesn't know what sensor it is?

    Poor idle

    With cj's reply earlier, he seemed to think it was due to the VVT constantly turning on and off? Given this is a very simple fix I will turn off the VVT completely (or change it to activate at 2500 just to completely rule it out), and see if this fixes my problem. The data means absolutely nothing to me, but I will give it to my tuner when I take the car back for a health check (and for him to fix the idle if I can't). Thanks for linking it. I will try disabling the VVT first thing tonight and I'm really hopeful this fixes the problem. I'm slightly worried that the ECU isn't picking up the wideband so it cannot be making any fueling adjustments.

    Poor idle

    Little more background, the car has a wideband o2 sensor from factory, and a plug and play ecu. So I would have hoped the ecu knew it had a wideband o2 sensor. Not sure what an LC1 configured in the ECU means, I do have a wideband on my dash but it isn't wired into the ecu. The car does have reasonably aggressive cams. I will disable the VVT tonight and see how it goes. Given it will only take out a little bit of power up to approx 5500, I'm not overly concerned. If I simply disable the VVT, could this throw out the fueling & timing? Given the amount invested in this car I'm going to call the tuner today and get them to fix it and do a full health check but I still like tinkering with it myself. Hi Adam, the injectors are Injector Dynamic ID2000. They are a bit overkill but when I purchased them the ID1600 weren't available and ID1000 wouldn't be enough for the power I'm chasing on e85. At they time they assured me these would idle fine on a 2L 4cyl engine, especially on e85. So I'm hoping this isn't the problem!

    Boost Issue

    Hi All, About a year ago I got my car tuned by a garage specialising in Link ECUs. The car is a 2002 Audi S3 and it made 460whp at 28psi on e85. Problem is, the car was dyno'd in 5th gear and driving around the street in second and third I don't get close to 28psi. So I have been playing around with "Boost Gear Wastegate Trim". The figures are set quite high and I'm still only getting around 22psi in second gear and I haven't had a chance to test 3rd gear to red line. The ecu knows what gear the car it is in I have already checked to make sure this isn't the problem. Do these figures seem a little high and potentially point to another problem, or should I just keep increasing them until I get 28psi? Thanks

    Boost Issue

    The car has only seen approx 1000km in this time, but I do intend on doing a health check. I will call and book it in today. Thanks for all your help!

    Poor idle

    I followed your advise and did the following: Switched to open idle ethrottle and disabled ignition idle control. I didn't change anything else and attached is a log. It idles different, probably smoother but still jumps around a lot. It automatically adjusted the throttle body % and the timing seems more reasonable. Looking at my AFR gauge they did jump around a little. Strange that the ecu doesn't show me AFR, maybe I don't know where to look. Any ideas as to why it's still jumping around a lot? I really appreciate the help! Log 2017-09-27 9;05;38 pm.llg

    Poor idle

    I'm definitely going to try what you advised in your previous post as I feel this could be the culprit as I saw the timing jump all over the place during the idle. Given when I unplugged the VVT it couldn't idle at all (just kept almost stalling), I feel that it plays some part, but I think if I increase the timing and decrease throttle as you advised it will help. Should this fail I'll be taking it back to the tuner regardless but would like to try fix this myself if I can.

    Poor idle

    Thank you for your help I will try this tonight! I think I have resolved the boost control, it just required very high figures in the gear wastegate trim which I was unsure if that was normal. But I will take the car to the dyno sooner rather than later to make sure all AFRs and timing is correct. This car has the exact same engine as the Audi TT. Given the previous response I will follow his instructions to see if I can get the idle smoother. I may also adjust the cam to switch at say 1500rpm to ensure this doesn't happen at idle, unless that will cause other sorts of problems?

    Boost Issue

    Thanks for the reply, The car does make 28psi in 5th gear with the current wastegate duty as seen from the attached dyno sheet. Only problem is the boost is quite a lot lower in 2nd gear and 3rd gear. Really I'm just wondering if 32% is too high of a figure in the gear trim. I will probably take the car to the dyno again for a health check to make sure all AFRs etc are okay.

    Poor idle

    Thank you for the reply! Could you please advise how I go about this, is it as simple as turning off the VVT? As far as I know, the VVT for my car only has two settings on and off, (car is Audi S3 8L). Is it possible to make the VVT only kick in after a certain rpm? As I'm having no issues after say 2000rpm. I hope this is the cause of the jerkyness I'm experiencing on light throttle.

    Boost Issue

    Here is the ecu file. Turbo GTX3071r Wastegate 39mm The picture shows how it is plumbed. Top goes to boost controller, bottom goes to charge pipe. I really don't want you to waste your time going too in depth, more just a simple yes or no whether its unreasonable to have such high values as I have to achieve the boost. I've checked for boost leaks with a smoke leak detector so I know that's not the issue. Really appreciate it, Thanks ecu26092017.pclr
