first off , for WOT , you actually have to floor it , lol. if not its useless. get the car in 3rd gear at 2k rpm , floor it instantly , hold it till redline. just like a dyno pull. if you want to part throttle tune the car , w have to first set the cam angles to do so , if you want it done , i can do it.


heres your map back with a couple changes. took a little fuel out of the entire high cam cause its rich as hell. took a shade of timing out of a couple spots cause you had a couple knocks. why its bucking like that , i dont know buddy off hand , you should check your plugs. your fuel map looks odd to me as far as its curves/smoothness.

Ok well that wasn't good, lol. I uploaded the new map and now the car won't start, I tried going back to the old map and other maps I've had but no luck. The car turns over but immediately shuts off :?: Any suggestions? Should I try clearing the security and what not?

Well I got the car back on after doing what you said, and ran a 3rd gear datalog with the right map this time (the one I posted earlier was an older one) and I will post them up tonight after work. Cranny with my foot to the floor the TPS read 98 so it is still a WOT run in case you are wondering, I may need to recalibrate the TPS though. Thanks again for all your help I really appreciate it.

The rev limit is because the engine coolant is 150 degrees.

So what is the temperature it should be at? The reason I ask is b/c if it is too cold it still happens when I've been driving the car for a while.

Normal temperature is 185 degrees. If you're below about 175, then look at your thermostat.

Thank you for all the help I will check that asap. So besides the temp thing would you say that the rest can be fixed with a new tune?

With cascading errors you need to fix the first problem, then re-test.
