Had some issues yesterday at the dyno. Am still there today. Any masters of EFI live willing to help I would appreciate it. Hopefully we will get it figured out but help is always welcome. Problem is transient throttle above about 3000 RPM. We load it and it goes lean above that. I have a couple guys working/helping on it but it can't help to ask. Apparently ther isn't a transient throttle table easily accessed in EFI like there is in tuners. I've seen guys come in here and answer questions say do this and that and it's fixed. Who knows.
It's twin turbo, 378 cid LS, E85, ID2000's, Magnafuel 4304 pump, return regulator, -10 lines feed and return. I might be posting this prematurely but after a few hours of beating our heads against the wall yesterday I don't want a repeat today. There is one more problem but I would like an answer to this one first. Need to add this is a COS and 3bar map.

 

Pm blk02ws6 or joecar

 

Is it happening while in power enrichment? If so, have you adjusted the table that commands how fast PE ramps up?? There's also a table (b3426 I think?) in the later f-body OS (2002) that's called throttle stomp compensation. I haven't messed around with this....but it might be something to look into.

 

Thank you my tuner says its not there. He did get the table found he was looking for. We are making head way.

 

Sorry - busy day and I just got your PM and email... Let me know if there is anything else I can help with.

 

Your tuner pm'd me early this morning regarding parameter B9021...

I replied explaining how to make it available (.cax file matching the OS in the PCM).

Keep us updated on your progress.
