  1. Hi all, I currently have my Bosch LSU 4.9 wideband attached to one of my exhaust manifold bungs (there are 3 on my engine, 2 in the exhaust manifold and 1 post cat) so I am getting readings from a combination of cylinders 2 and 4 which is giving me a stable reading. I have a full race manifold to go in which doesn't have any O2 bungs in it, would it be ok to use the post cat bung location or should I see if I can get a bung welded into the pre cat pipework just before the cat? I am guessing that the AFR would be slightly different post cat, however I know that a lot of dynos use an exhaust sniffer in the backbox which would be post cat for tuning. The engine is currently NA but will be running a turbo at some point in the future (with a bung in the downpipe pre cat) - was just wondering if I would be ok to run the wideband sensor in the post cat position until I swap to the turbo setup - I guess I could log the AFR in the current location and then again in the post cat location to see how much it might be different - guessing something like 0.5 AFR points perhaps. Anyone have experience on this matter? My current fuel table is pretty close to the target AFRs I am aiming for and am currently using the auto fuel correction option to adjust where needed - not wanting to run the engine lean if its trying to fuel differently to the current table. Thanks in advance!

    Quick help with speed calibration

    Hi all, My digital input for my speed (from the stock ABS ECU) measures 1HZ for each MPH, currently trying to work out the calibration number I need for the wheel speed to allow it to make sense (plus able to use it for launch control etc. Currently have it set to 3 and here are a few examples of the input and speed output: 3.4mph = 407.8kph 54mph = 6480 kph 62.6mph = 6553.5 kph Just trying to work out what I need to change the calibration figure to so that the readings match up, thinking its going to be less than 1? Worth noting that the stock ABS unit takes all 4 ABS sensor signals (think they are 48 tooth) and then works out the speed and sends a single signal to the stock ECU/instruments. This is going to be a bit of a faff when it comes to sorting out traction control as I guess I am going to need to splice into 2 of the ABS signals directly in order to be able to get driven and non driven wheel speed - but just want to get the logging right first. Worth also noting that the Link ECU doen't drive the stock instruments, the stock ECU does as its currently running in piggyback for certain systems although 95% of the engine is being run by the Link ECU.

    Which Bosch knock sensor?

    Hi all, Can anyone tell me which knock sensor I need for better knock control etc rather than using the stock 1 wire knock sensor as per OEM etc. Thanks in advance!

    Logging automatically at a certain temp?

    Ah, thank you for that, I will check out the software later for the filters etc - although might be an issue if its already taken 1000 samples by the time the engine is up to temp. Will look into the virtual aux option though as that seems to make sense to use.
  5. Hi all, I have been gradually refining the map on my car with road tuning and logging, then using the mixture map to find cells that need a slight tweak - most are now within 0.2 AFR or less of the target AFR which is great. My question is around being able to automatically start logging when a certain parameter is met, I can see that I can set the logging to start at a certain throttle input/MAP value etc etc however I can't see how I can start the mapping with ECT. At the moment I am manually starting the logging once the engine is up to temp where there isn't any fuel adjustments taking place for cold start (with CLL off), I could set it to start logging once the engine sees a certain vacuum on light throttle however I usually want to capture all of the data from idle for a whole drive rather than just parts of the map. I see that with quick tune there is an ECT lockout so that it can't adjust fueling when the engine is cold - trying to replicate this with the normal logging. I also notice that each cell seems to have a maximum of 1000 samples - is there any way of increasing this or should I reduce the sampling rate? I have set the sampling rate quite high as there are some cells that I wanted to capture data for but aren't often in the cells - such as WOT. Thanks in advance!

    VVTi - link to TP% or MAP?

    I agree with the MAF being a better option, however the stock MAF is too restrictive for the airflow I am planning and running a MAP sensor tidies everything up.

    VVTi - link to TP% or MAP?

    Thanks for that, yeah it seems to work fine at the moment, might look to swap it to the MAP as the load axis - they are probably quite similar as 100% throttle would be max load, I guess its the part throttle bits as you mention might be a bit different. I will look at other VVTi maps in the basemaps and see if there are any which are known safe settings but use the MAP rather than TP.
  8. Hi all, I have recently copied over the table for VVTi from the WRX V10 basemap as suggested, the table is linked to throttle position rather than load via the MAP KPa. Should I look to link to to the engine load or keep it linked to throttle position? The engine in question is a Toyota 1zz running NA, happy with the fueling and ignition at the moment but just want to make sure the VVTi is working as best as it can safely. Thanks in advance!

    Can't connect via usb to ecu.

    I was about to say, I put the USB cable on my Xtreme into the CAN port rather than the COM port - its the same connector, although not sure if its the same setup on some of the plug and play ECUs.

    Rich AFR causing knock? Issue with knock setup?

    Many thanks, I have copied over the Monsoon ignition table into my current map, turned knock control off, I have also noticed that there is a setting that seemed to be advancing the ignition timing when the engine was cold/warming up - its retarding the timing top end which is correct but have zeroed out the timing advance when cold. I have kept the VVTi table as it is - there are some tuned valued in there from the file sent over from the engine it was tuned on. Next on the list to sort is the temperature gauge - its out by around 8 degrees C and also the speed source, will be looking to use an ABS sensor to get the direct signal (although its a 48 tooth ring) - DI1 speed source is already in MPH but I can't seem to be able to use it. I have set the calibration to 1.6 as there are around 1.6 km in 1 mile (the speed source arrives from the ABS ECU as 1hz = 1mph - rather than the frequency of the actual ABS ring). Looks like I will have to get the actual sensor data from the ABS ECU to be able to use traction control though.

    Rich AFR causing knock? Issue with knock setup?

    Thank you, I am running high octane fuel as well which is why I was wondering why it was showing knock at quite retarded ignition timing, think it might be a false positive - I was thinking mid to high 20s would be about right for ignition advance as you mention - will turn the knock control off until I swap out to a better sensor and start to look at running boost. Should I update the VVTi table as well or just see how the monsoon ignition map runs first? I know the VVTi table isn't something you want to mess with etc. Thanks again for your help on this!

    Rich AFR causing knock? Issue with knock setup?

    Its an NA engine, I will be turboing the new engine (fully forged) at some point but will initially also be run as an NA - will be going to a tuner when I do go turbo on the engine though. Just looking to get a solid map running on the car that might not be 100% fully maximising the engine but will still be a step up from the OEM ECU.

    Rich AFR causing knock? Issue with knock setup?

    I am guessing there isn't a way to road tune the car using the narrowband knock sensor to get in the ball park? I know it won't be perfect without a dyno and better equipment but was able to get a rough idea where the limits were on the stock knock sensor and the PFC. The fueling is pretty much there now with the majority of cells being within a small margin of error vs the AFR table. I am tempted to copy over some of the tables from the basemaps for the ignition and VVTi - at least I know those values would be safer? I noticed that on the 350z map the ignition timing at the top end at full vacuum is at around 22 degrees whereas I have retarded my map back to around 10 at the top end - have I retarded the map too far? It's about the same on the Monsoon basemap, I am happy with my fueling table as well as idle, cold start etc even without closed loop enabled at the moment, should I: Copy the ignition table from the Monsoon basemap Copy the VVTi inlet table from the Storm black basemap or 350z basemap I will be getting a decent Bosch doughnut knock sensor - issue being is that its impossible to get to at the back of the engine, will be swapping it out when I put in the new engine - the current engine is simply a test bed as its high mileage so not too concerned if something happens as its a learning platform for me to get the Link all setup ready for the new engine. Is the knock logged if the knock control is turned off btw? Really sorry for all the questions, I know there was a marked step up in drivability between the stock ECU and the Power FC when tuned, currently the Link feels like its holding back a bit and I know its probably around ignition looking at the PFC map I have. I think my issue is slightly compounded by the fact that the engine is high mileage as well as the gearbox so there would be additional noises and resonance going through the engine which doesn't help!
  14. Hi all, Currently doing some road tuning with my Link, I seem to keep coming up with an issue where the knock control keeps coming on and pulling timing, I have a feeling it might be a false positive as it coming on at sometimes only 10 degrees advance and I have pulled a lot of timing out of my map. I have attached a log of the last logged run, knock control is set to 7khz as I believe the 79mm bore knocks at 7.3khz, my MAP sensor is reading full vacuum in the high 90s on WOT - on WOT the fueling seemed to drop to around 10.5:1 however I am unable to tune these cells as the knock control was active so it doesn't seem to log it on the mixture map. Is there an issue with my knock protection settings? Does running rich trigger the knock control? Please also note that the speed isn't reading correctly and the coolant temp is around 7c too cold vs the sensor reading. Basically just need a hand trying to see if I am getting a false positive on the knock readings as I really don't think the engine is knocking - previous tune on the PFC has ignition advance at around 32 degrees with very little knock.

    Installing monsoon into 13b pp help

    Do you know if there is anywhere I can view the help file offline? I sometimes want to check something during lunch at work but can't as I don't have PClink on my PC etc, I do however agree that its very helpful.
