    Poor Idle

    Thank you for the comprehensive reply. I'm going to read through this a few more times and have a play around tonight. Really appreciate it

    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

    Poor Idle

    Quick summary: Car runs on e85 with large injectors, I believe this is the cause for the poor idle. Had the car retuned to compensate for the injector low pulse width data previously, still not 100% The problem: Idle does jump around a little, I don't expect a factory idle but I would like to try and improve it as much as possible. Main problem is when I rev the engine when it returns to idle it goes far below. Idle is set to around 1200rpm and it goes down as low as 700rpm. When the car is fully warmed it doesn't go as low, probably only to 1000rpm or so. Log attached at approx 60 degrees which I believe should be warm enough for the car to run great. Also, the idle is set for 1300-1200 rpm but it never hits these figures and I'm unsure why. If anyone could give me a list of things to try to improve the idle and stop it dropping so low when I rev the engine, that would be fantastic. Alternatively, if this requires detailed tuning and you know of someone who can remotely tune the car (just the idle) I'm all ears! Thank you! poor returning to idle.llg idlesokay.pclr

    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

    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!

    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

    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
