Update...
So i got a note to lower the timing to 15* & 18*...same thing....dosent seem as bad though....any thoughts TB ????

In some cases the maf can pick up interference from the alky pump. If that is the case you would see it on pl log. The maf signal on the graph would get real choppy and erratic. In this case the power for the translator or alky system needs to be moved. I ran a hot wire off the alt to a relay under the dash that runs alky and a couple other accessories.

Did you try a zip the log then attatch? If you still can't attatch, send it to my email. turboburick@sbcglobal(dot)net

Ah ha !!! finally figured it out.... Just took one step foward...now im waiting to take 3 steps back...FML !!!

Had a quick look and going by your WB02 (i assume you have it hooked to powerlogger) You are running pig rich

 

[Soldier_GN]

Yes PLX WBO2 connected to PL...pig rich...really ??? How far down would i recommend i take it ??? Im at the base right now... I got 42.5 LBS injectors... It should be at 42-43 LBS stattic with vaccume off right ??? and then dial it down...but how much...what kinda #'s should i be looking for on thw WBO2 ???

 

[86gn]

replied in the PM

 

[TurboBuRick]

Yep, wot is rich. Is alky on? Only 17 psi boost?

[TurboDave]

File 000: I see you now have a boost signal so you can ignore my last PM. TPS only 3v !!?? WB reading 10.00's !! ?? WAY rich!!

File 002: same. TPS WAY LOW!!!!!!!!!!!!!!!!!!!!!! WB reading WAY RICH (wb appears to be working normally) at 10.00's !!!!!!!!!!!!!

 

[Eric Stage I]

It's too rich for that low boost, since the chip was made for 23-25psi, and you're only running ~17psi. If you keep the boost that low, then you'll have to back the alky and fuel down until it cleans up.

You won't need much alky for that kind of boost (17psi), so you might try turning it down a couple numbers. If that's not enough, then reduce WOT fuel using the chip adjustment.

The other option is start turning the boost up. Be careful and watch for knock.

Regards,
Eric

Plan of action...
Start 14 # of boost and work my way up to 23-25#'s. Gona fix the TPS @ WOT, set it to 4.5. And see what happens....Thanks again to everyone for all your input, without you guys id still be stuck holding my you know what....Well see what happens in the next few days....Thanks again TB...
