msl = log. msq = tune

Its been a while. Tuning has not been going well and I just haven't had time to mess with the car. Here is my current msq and a log. I would appreciate any input you all would have on how I could improve this tune. The biggest issue at the moment, besides seeming both rich and lean under certain circumstances is that it doesn't respond when i go to blip the throttle.

That would likely be transient throttle, or whatever the MS software calls it.

Basic concept is that when you blip the throttle the engine sucks in air and there's a small delay before the MAP can show a reading.

So the ECU needs to know that when the throttle blips, it needs to just spray some fuel for a moment to cover that small delay before the MAP catches up.

Probably not the worlds best explanation, but should cover the bare basics.


For MS specific, try reading this:

Makes sense. I will definitely look into this.

Just don't touch it until your map is decently tuned. You'll end up chasing your tail as to where what why who when is giving fuel. Tune the map at "steady" state (as best as possible) - then when that's settled, play with the AE.

I think I have made some significant progress tuning the car on the GT500 Injectors, and everything seems to be running well under 4k rpm (think im going to let a professional tuner handle high rpm). My plan is to try to get the turbo parts installed and the car running properly, avoiding boost, and then take it to a tuner and let them handle all of the finer tuning.

I'd appreciate any feedback I can get on my current tune. I've attached the tune and a data log below.

Is there a trick to uploading .msl's? I can't get my log to upload.
