Has anyone noticed a different A/F ratio a few weeks after a tune?

Mine is having strange symptoms.. I got her tuned a few weeks back.. steady AF from around 11.1-12.4 depending on gear/speed..

But suddenly it actes strange and i'm non stop hitting 12.4 raising to -> 13.X when going into boost for about 2-3 secs...


I already asked here: https://www.s2ki.com/s2000/topic/885...ge-af-reading/

Could it be that the OEM ecu is relearning itself and messing up the maps? But that couldn't be the case when going WOT since the ecu doesnt use a map that "learns during driving" so i'm realy confused about this one..

I got a AEM UEGO wideband mounted right before the 3" berk HFC...

Thanks for helping out! The tuner is on holiday so i can't ask him right now

 

Is your boost staying constant? Could be boost spiking higher than normal causing a leaner condition.. Have you changed anything recently?

 

No, im only running 5.5psi and i have a ported wastegate... Only thing i changed is that i added a turbo timer...

All the tests i did were also under 6K rpm..

Checked the uego wideband today and it was not loose or something..

Im clueless!

 

He and I have e-mailed back and forth a couple of times. He's open to it, he just needs a car there to fabricated it on, which is impossible for me since I live in CA. I believe he's back east somewhere.

The T25 is somewhat of a choking point but I've made 360+ rwhp on the log manifold using a GT3071R and I can only imagine how much better it would be if it was on an ELM.

 

I would be down for a new mani somone just needs to make a stage 2 kit and have a group buy! I know for a fact atleast 20people including me will fork over cash for a hybrid stage 2 maybe a new mani and turbo? Bigger downpipe. TALK TO PANG!

 

How close is this to becoming a reality? I might just hold off on buying the replacement manifold.

 

Same here!

 

Again, someone close to Pang ask him and it could be close to a reality, otherwise it's just a pipe dream at the moment.

 

somone plz! Talk to him I'll hold off on buying my replacment. We should start a new thread?? Lol

 

what's really sad here is how many people NEED the replacement manifold from Pang. greddy manifold
