Idle is a little rich, your BPW should be in the 1's.. not the 2's. Not terrible though. I wouldn't worry about that at all.

Overall i'd say it's running pretty well, your o2 volts look great. BLM's are slightly rich but not enough to mess with (unless you really want to).

you seem to have a lead foot though.. 95 MPH? lol

[Alxsmt]

really? thats untuned with 2.8 injectors... the af seems to be good according to my gauge but i kinda thought it was lying to me lol

and yeah i got carried away.. i calmed down after that

would that rich idle affect my hydrocarbons? there at 400 and need to be 250 for deq. im thinking it is

did it show when it died? almost at every stop...

[Superdave]

are you emulating as well?


I bet if you pulled a little bit of idle fuel it would help. I'll look more into them and see what's going on when it dies...

[Alxsmt]

yeah runnin the bfuz file. i bent the throttle cable bracket so it idles at 1100 and it was fine for a while but i think the braket went back

today im gonna have the shop set the idle at 1000 (i couldnt find it lol). swapin my new balanced 28# injectors in too

thanks im acually somewhat understanding the ostrich now, maybe after i watch it get tuned i will be able to do it my self or at least trust my self to tinker with fuel and spark or something

[Superdave]

you set the idle in the binary file, not by bending the throttle bracket

Bending the bracket can cause all kinds of issues, the ECM needs to see the TPS at 0 so it can switch to BLM Cell 0 and use the idle fuel table. Holding the throttle open also messes with the idle MAP threshold.

It's very easy to change the idle, find the table "idle RPM vs coolant temp in drive" and adjust the values there. The P/N one dosen't do anything in a 5 speed bin.



what injectors are you using now? you'll probably have to re-calculate the BPC to run the 28lb ones..


are they 28# @ 43PSI or at 55PSI?

[IsaacHayes]

Yeah, having the throttle open will make it die and act funny cause it thinks you are holding the throttle open cause the TPS doesn't read 0, and like Dave said, then it won't switch to the deaccleration/idle etc settings. Hell I put my TPS back on once and it wasn't quite right and registered higher than 0 and the car was idling high as hell, even though the throttle was closed and the IAC counts normal. The car thought I was giving it gas so it squirted more fuel.

Get that throttle cable back to normal and verify TPS is at 0% at idle.

i reset the ecu to it reads at zero.. set the idle at 1500 and it still likes to die. also i went into a shop today to get it tuned and swaped out my injectors when i got there. ran like CRAP, missed really bad.. they didnt seem interisted in messing with it so im gonna try my self. also with the 2.8 injectors (put em back in) its running a 15.2 qtr mile with a 11afr at wot, that was the richest it got.. im trying to get a data log but its messin up so i will try a few more times tonight b4 i leave the track
