So, I started another thread, but now i'll include vids...

In the last week, I installed a:

1) Walbro fuel pump (using Phunks instructions)
2) ATI Procharger kit (not running belt ie no boost until tuned)
3) MotoryDyne 5/16 iso-thermal copper spacer


And now, as you can see in the vids, I am getting some weird issues. What you will see in the below vids is me...flooring it through 2nd gear, notice the power is fine. As soon as I shift, i'm flooring it again...notice that there is MINIMAL acceleration...then I let off the gas briefly, and go back to FULL THROTTLE, and there is back to normal acceleration.

WHAT IS GOING ON?!?! I've already tried the Throttle position reset and ECU reset.

any ideas?!

 

I seem to get a little of that to a MUCH smaller degree on my 100% stock engine....

 

maybe it has to do with the timing or maybe you DO need a tune?

not sure, never had the problem though, just throwin that out. odd though.

 

ok, so hal from Injected Performance helped me get setup here...sent me a base map for the Haltech that would let me plug it in and still use all the stock ECU settings...

This gave me access to the attached chart.

As you can see...the throttle position is reading correctly...0 to 100...but for whatever reason, on hard shifts...the injector fuel time is getting cut in half (roughly) until i let off and get back on it.

aka...no problem for tuning it out according to hal!!!!

I go next tuesday for my tune!!! giddyup!!!!


edit:
top graph = throttle position
bottom graph = injector fuel time

 

U need tune.....
