data log little red s10

[lilhupper]

ok hows my idle log looking?

[lilhupper]

ok got my new pump in seems to be running a little better got a data log with the cutting out when costing. the cutting out at cost was right around 5.40 min

[EagleMark]

Sure got richer in the lower RPM and idle areas!

What kind of distributor do you have in that?

Do you have an EGR valve?

[lilhupper]

No egr and factory distibutor from orielys

[EagleMark]

Well if I turn off the EGR this time... that will get rid of 6* extra timing! So that leaves 4* extra timing I'm guessing is in an aftermarket EST/ICM module that came in that distributor?

I think your stall is a misfire from to much timing!

[lilhupper]

well the icm is a factory one came off a factory distributor. might be a little off on my timing last time i set it i had that idling problem

[lilhupper]

my cam is also 4* advanced

[EagleMark]

I turned off EGR, that was my mistake, I had notes but forgot? Sorry...

Set timing to 0* with bypass disconnected.

Looks like you've been playing with min air screw again? If not something is wrong like TPS loose? Maybe even worn throttle shaft causing a vacuum leak? Anyway we have no IAC counts at idle and TPS voltage is low. So turn screw in 1/4 turn and leave alone.

You've finally got plenty of fuel!

Adjusted VE tables and will mail you a chip!

[lilhupper]

ok sounds good ill get right on that

Wait a minute? No IAC counts at idle would be turn screw out 1/4 turn! I had that backwards. But TPS voltage is low, so after turning screw out 1/4 turn, you will have to adjust TPS sensor by loosening the screws and twisting it, use your data log to try and get .54 volts.

ok i havnt had time to mess with it yet ill try to this weekend just dropped 6 in of snow so no more driving logs for a while

[lilhupper]

got truck timed to 0* and 1/4 turn on the air speed screw. truck feels good did have some problems with stalling but didnt seem to do it today. ill try to get a of of it soon

Back on the first page... 8 months ago we were working on getting the throttle blades set right with the IAC count dialed in to a low number. This log looks good there. Don't touch it anymore!

Not sure why your having a stalling issue sometimes but from log I can guess it has something to do with cooling system? You run fairly consistent at 195 ish, but when you come to a stop and idle it climbs to 228 and even bounces around 10*? This is throwing off fueling and spark as they both try to compensate for an engine that is starting to overheat! For instance your idle BLM varies from 112 = good, to 152 = bad. None of the other areas have this kind of variance. Timing also changes by 6*...

Some of the low MAP/deceleration is pretty rich, rest of the BLM in table are good, little low of 128 and right where I like them. But I looked at your last log and didn't have this issue? Unless you changed the chip? Something else has changed? Have you changed fuel pressure or?

[lilhupper]

Fuel pressure is the same. I did change the chip. I have dont nothing but timing and ait speed screw

[EagleMark]

I have dont nothing but timing and ait speed screw

What does that mean?

You should have told me you changed the chip! I wasted over an hour trying to find why you had more timing in certain areas then I had programmed! All is OK except for Idle at end of log when it was getting hot was WAY to much. It seemed to add timing when hot instead of take away...
