Apparently I'm not smart enough to zip the files down to size in order to attach them, can anybody help and enlighten me?

Altezza Beams ECU on a 2jz GTE (E-throttle) develops an oscillating idle pattern during warmer weather when fully warmed up and after decelerating and coming to a stop. Strange thing is it idles normal when the a/c in on, although I rarely run it in this car. I tried playing with the Idle Timing table but I really don't have a clue what I'm doing. Any suggestions on what settings I could possibly experiment with to get the idle back in check? Intake idle temp when fully warmed up with our current climate is around 104* F.

Adam Another email sent with logs FYI.

I will give that a shot, thanks so much.

I've attempted to attatch new tune and log with One Drive link, firmware has been updated FYI. No codes were thrown with E-Throttle "on" but I'm still not 100% confident that the current settings will prevent that from hapening at some point. I'm still working on wiring in a VSS soloution unless the infrequant stall issue can be tuned around, because the pinout has me a bit confused at the moment. https://onedrive.live.com/?id=AC1E3E4F4E584FD3!105&cid=AC1E3E4F4E584FD3

In reference to above post, I also expanded the E throttle 1 table Axis on the rpm side, 0-500-100-1500-2000-2500-3000-4000-5000-6000-7000-7200. Just FYI. KR

Adam, I turned E Throttle to "on" and went for a drive. I got an error fairly quickly and it went into limp mode. I put it back into "setup" and got everything going again. I logged 5 runs after returning it to "on" mode but never got a code/ limp mode, but the rpm's are hanging up again and not coming down to the proper idle. I zipped the last run and attatched it, could you give it a look and see what you think? The car seemed to perform really well in "on" mode other than what I described. On the startup on this log you will see flucuating around 1000rpm, I changed 0-1000rpm to 3 as opposed to 2 and that solved that problem. Once again, I don't know jack about it compared to you. Thank you, KR 112720 E Log 5.zip

Adam, could you please take a look at the e throttle settings from that last log I sent and see if perhaps you could "improve" them? Meanwhile I've been in contact with Panic Wire about the vehicle speed sensor that apparently hasn't been connected since I switched to a CD009 transmission. Going to try piping it in from the ABS ecu I think. Thank you, KR

I will look into the speed sensor issue. I was able to send you a driving log in the previous post, just not another cold start. I’ll look into the methods you mentioned on future logs. KR

TONS smoother, idle/drop worked great! The engine did die once at a stop towards the end of the log, don't know if that is E-throttle related or what. I logged a complete cold start and a stint of driving and they are attatched. Thank you so much. 112320 Regular Driving.llg Both files exceeded the max limit so the new cold start is a no go. I tried it in an additional post and it wouldn't go despite only being 2.7MB.

Sweet, thanks so much. KR

I get it, I have an Innovate SCG-1 that controls the wastegate and wideband and will dump pressure in the event it goes lean or over boost's but I will be discussing the Issues that Adam discovered.

Adam, here's the log you requested. I cold started it and immediately hit record, (I didn't know if turning it over would lose connection with the ecu). You can see initially see that as I pulled out of the garage the RPM's hung up at 2K, I engine braked it back to normal so it could warm up at 1K. Upon normal driving after warmup, it clearly starts acting up. As stated earlier, make ANY changes you deem neccesary and thank you so much. KR 112120 Cold Start.llg

That is disapointing to hear as the performance end of the tune is incredible. Adam, since the tuner is out of state, I would love nothing more than for you to adjust anything and everything that you deem fit, and it would greatly be appreciated! I will get the log you requested heading your way. Thanks so much. KR

Update I raised the Idle Ignition control RPM lockout to 1650rpm's (from 1500) and it seems to have fixed the issue. I don't know if that's the best way around the issue but it seems to work great.
