Sent it to ATI for a rebuild...they supply the shells

I did make some additional changes to warmup...still an ongoing process. No older logs except the one in the earlier post in this thread. I tested the intake for leaks and it all tested fine. It runs like it wants to go but just can't really rev up. Is it possible the CanLambda is messed up? New 02 sensor in it now. Would cracked exhaust cause the symptoms? Haven't thought of/looked into that possibility.

It's been a long time, but I made the adjustment to the map and put the car away last fall. I pulled the car out in the spring and it started destroying the serpentine belt....2 ATI damper shells later I discovered that the alternator was seizing and causing the issue. All back together and now another issue has come up...it now runs lean on acceleration (lambda 1.5). Only changes to tune have been related to starting and idle (at least it starts well now). I've done a file compare and don't see any obvious issue that I have created with the start/idle. Have replaced the MAP sensor, O2 sensor, plugs/wire and coil...no change. Map sensor is an Omni Power 2.5 bar...Could it be that I need to set the MAP limit to 245? rather than 250 (sensor limit)?? Have attached the current tune ...any insight would be much appreciated. Log file attached in next post Sept22#2.pclx

I thought of that just after I posted, but I thought I was fine. Did realized it had a 10kPa control range. I will make appropriate adjustments. Unfortunately this was the last track day for the year and it will be a while before I get to test it out. Thx

Running into an issue with my Mini Cooper that I can't get a handle on. Car ran fine in the spring, then at a summer track event it started acting like it was running into a rev limiter at around 4500 rpm in 3rd and 4th gear. Had a look at my AIM data and it looked like the ECT was dropping to -40, so suspected the sensor/wiring. Replaced the sensor and the wiring harness and went out to the track this morning and same problem, but ECT looks fine. Replaced the MAP sensor (new)...still same issue. Now I suspect something in the current tune, but can't see anything obvious to me. Have included the current tune and a log of today's issue (see late in the log). Any help would be appreciated. I've obviously done something stupid, but can't find it. Mini Missfire -2021-10-23 10;10;00 am.llgx MiniOCT21-tune.pclx

Perfect...all cleared now. Race car--has master shut off...just changed the OBD setting and everything is working perfectly. THX

Nope...didn't work...ECT still pinned and red warning light on (after cold start). AIM Dash shows 16C which about right for the garage. ABS etc warning lights stay on. Maybe I still have it set incorrectly. 1QWK_NEW_Test.pclx

Finishing up the setup on my R53 and noticed that the Speedo/instrument cluster isn't working properly. ECT is full max and all the warning lights stay on. I suspect that the CAN supply to dash needs some configuration or?? CAN 1 is configured for CanLambda and Aim MXL dash. Do I configure CAN 2 for MiniLink? and what is the proper setup to get the instrument cluster back to proper function (worked fine with the old Vipec) Thx

Thanks Adam...will work on it tomorrow...I'm in Canada so late here.

I just saw in another post that Evans has a training course for the G4x...I can't find any contact info. If I buy the course is it accessible for life or limited time?

ADAM---YOUR THE MAN Idles quite nicely. I returned the fuel and Ign tables back to the original Vipec settings before trying your fix..file attached...thought that might be the best place to start. I made changes to the warm up enrichment and played with the fuel table a little...running pretty rich at idle...file included and a log. Do I correct the Lambda in the fuel map or is there somewhere else to adjust? Accel enrichment also needs a little work...rpm drops a lot on return to idle...see late in the log.

Thanks Adam...Map sensor is not a stock Mini unit...it is one provided by Jan at RMW to counter the problems with the stock unit at higher boost (when I was still running the TMIC). But at this point with the FMIC I don't get anywhere near the same boost and could actually go back to the stock sensor. Will give the new idle.pclx a go.

BTW--full race car, idle target is 1300. Running TVS S/C, FMIC, CatCam 279/238 deg on 100 octane gas

I recently replaced my Vipec with a G4x. I was having issues with throttle causing it going into limp mode. Due to COVID Lockdown here I can't take the car to anyone to set it up, so I have been learning more about tuning and working on the transfer myself. Unfortunately the files don't transfer directly, so I have been transferring the important parts of the tune manually and the car now runs. I have started with getting a stable idle (also a problem on the Vipec) and E throttle setup at 0 APS seem high and I have need to lean out the fuel table and reduce the timing to get a stable idle. I think I must have something fundamentally wrong somewhere. Maybe someone else can find it. Attached are 2 previous Vipec files, current stable G4x file and a log of stable idle. Any help would be appreciated.
