Hi, I have a problem tuning up my ZE, seems like the ECU doesn´t store the information after exit diagnostic mode, idle and timing go off. I read some post and I find that some ECUs needs to remove the jumper wire before stop the engine, this is true? how can I know what is the correct method for my ECU? I allways removed the jumper after stop the car.
Thanks a lot.
How to store tune up data on KLZE ECU
Re: How to store tune up data on KLZE ECU
I try to exit diagnostic mode this morning with and without the engine started, and my timing ups to 15º allways, RPM ups from 750 on diagnostic to 1000 in normal mode. The timing should advance if the engine revs up? is normal that I got 10º at 650RPM and 15º at 1000RPM?
Re: How to store tune up data on KLZE ECU
Disconnect your negative battery cable and hold the brake peddle down for 15 sec's. This will clear the ECU's memory. Go into diags mode and try again. I always jump or disconnect from ten and grd with the engine off. Once this is completed let the engine run for at least 15 mins so the ECU can relearn the settings.

I know you believe that you understand what you think I said but I'm sure you realize that what you heard is not what I meant.

I know about the ECU reset, I allways did it before any tune up.
Anyone knows if timing should stand at 10º on any RPM range?

Re: How to store tune up data on KLZE ECU
The timing will automatically advance to the optimal setting when you increase the throttle. Not sure how high it goes, but it sounds like its working right.
