Hey guys Im trying to work on my pump gas tune.
I have not been able to change fuel much because my wideband is acting up and showing Im running lean.
I have been adjusting timing and running about 21psi. 3bar looks pretty good
I was not able to do I full 3rd gear pull.

Let me know what I should look at.

I would like to run about 25psi if I can get there.

Thanks

Have you tried using the other AEM inputs? I know the AEM is not the greatest with DSMlink.

Do you have a gauge with the AEM? If so, how does it compare to the logged values?

Also, I would recommend getting the V3 software and working with that if you can. It's a much nicer interface.

Do you have an AFPR and is your fuel pump rewired? If not, I'd work on both of those items.

Yes

Dsmlink and guage match. I have looked for exhaust leaks cant find any. I know its off because its saying im running high 11 a/r on pump and Im not really knocking enough to be concerned.
Its showing the same a/r as when I was 110 oct a few weeks ago with alot more fuel pulled out. Now I have added fuel with no change.

Also, I would recommend getting the V3 software and working with that if you can. It's a much nicer interface.

I down loaded it the other day just have not had a chance to look at it.

Yes I have afpr and rewired 255
 
It will be very difficult, if not impossible, to spot exhaust leaks. You'll need to run some seafoam through the motor, or have a shop perform a smoke test. That's the only way I was able to find out that my flex section was leaking.
