My car did not like the 26.2 either. Was laggy as hell at 80 and 28 settings which I tried to adjust but without much suscces.Flashed back to 25 and all problems solved as it also run great on it before.
Btw. I also run the old bms RACE AT flash with E40 mix and the car runs great.
Don't feel as reflashing would change much for me at this point.
Installing the 255 inline pump this weekend as I finally got all the right hardware for proper install.

I noticed the hard/jerky transmission shifting too. Also noticed a teeny bit more rattle when letting off the throttle abruptly. guess this really does mean all cars/turbos/wastegates are different, since majority of people report deceleration rattle to be gone. 26.2 seemed better under wot, but I went back to 23g, which seems to be the best all around for my car so far. menu 10 is set to 65-70 and menu 12 is set to 34

I just set 90/2.0 for the menus 10/12. Don't know what they exactly mean, but the setting seems to be working. It did once created a very distinct exhaust on WOT 2nd gear over 3000 rpm. I still get a slight rattle, but it quickly disappears.

So for the problem with rattling occurring when letting off the throttle abruptly in 1st, 2nd, and sometimes 3rd gear, do you suggest setting menu 12 lower or higher? I believe that menu 12 controls this portion of the waste gate positioning, correct me if I'm wrong please.

Send a log over of it. ISO25 holds the wastegates shut when letting off the gas, while ISO26 lets them swing open to relieve pressure. I believe the ISO26 approach is safer for the engine. But, may make it more prone to rattle for an instant when letting off the gas. If it happens in ISO25 also though then you simply have menu 10 set wrong.

So do you want me to flash back over to iso 25 and record a log of me letting off the throttle abruptly in 1-3 gear? I am also going to test out setting menu 10=80 and 12=20 tomorrow, going to see how that works...

So a setting of say 80 in menu 10 would be 4 on the rev counter right? And 12/20 would be 1?


fuel injection is cool, but i'd rather be blown!

So I have noticed that my car keeps switching back to map 0 randomly. This has been since I updated to ISO 25 . Would the ISO_26.2 fix this problem and is it related to the obd2 port switching me back to map 0. I assume the fix in ISO_26.2 is to fix that. I thought I was loosing my mind....

This problem was specifically fixed in 26.2, see the release notes on page 1.

If you want to send a log of the "issue" on ISO26 I'll check it out.

I also noticed that the JB4 was switching back to map 0 on ISO 25. I updated to ISO 26.2 and that corrected that problem, but now the CANflap will not stay open. It keeps closing after a few seconds. I wonder if there is some kind of conflict after my recent BMS pump gas flash.

You may be right. I think I have noticed the similar thing yesterday. I haven't flashed yet though.

After flashing to 26.2, rattle is back with a vengeance, even with menu 10 at 80.

Email a CSV log of it rattling. Have some changes in 26.3 that should resolve it assuming 25 was working.

26.2 worked fine with my car until I flashed the DME with the latest BMS pump gas flash. Low RPM driveability sucks and after three days of trying, I can't find any combination of menu 10 and 12 settings that resolves it. I'm just about ready to flash my DME back to stock.

If you want the JB4 to ignore the flash map throttle mapping then set fud to 96.

Thanks, Terry, I'll give that a shot. The car accelerates smoothly above 3K RPMs but is anything but smooth below that. What's the best starting point for menus 10 and 12? I think I've dropped 10 down to 50 and have 12 around 35 right now.

I would try flashing the jb4 back to 25 firmware. That's what I did when 26.2 sucked on my car .25 works great with backend flash.
Btw. I am 2008 AT fbo E40 with bms meth.
