data log little red s10

[lilhupper]

Sorry I forgot about the chip. Ill ive done is adjusted the air speed screw and tining like you told me to.

Those spread out BLM numbers at idle may be from to much timing? Not the way distributor is set, but in chip? I don't know what you changed there but when it was hot at end of data log you were hitting 28*. Earlier was 24*, the last chip I sent was set to 22*. So it may be to much timing causing knock, misfire or?

[lilhupper]

Ill check timing again and make sure its dead 0*

[EagleMark]

The timing I see in data log would not be affected by your distributor setting.

You said you changed chips? So it's not the last chip I sent I have no idea what is in it?

[lilhupper]

it is the last chip you sent.

[EagleMark]

it is the last chip you sent.

A few posts back you said:

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

So I'm confused!

[lilhupper]

This is the first log from the chip you sent 6 months ago.

[EagleMark]

The last chip I sent was in 11/13 so about 4 months ago. Why would we do a data log on an old chip that has been adjusted? What exactly are you trying to do, I don't understand at all?

[lilhupper]

Sorry 4 months this is that chip

OK, so we are back to this post...

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?

I didn't see much wrong in the short log except what is noted above. Just some fine tuning of decal, which is not going to help the only issue you noted of stalling sometimes and on this log it did not. Since the seasons have changed I'm guessing the temps are much warmer then when we left off? There's not much I can do with the idle or stalling when Coolant temps go to 228* when you stop cruising and come to idle. Actually I think it was boiling as it bounced around about 10* there, is there a correct 50/50 mixture of water/antifreeze?. Is this vehicle mechanical fan? Does it have a thermostatic clutch? The cheap cluth replacement is just a slip, it does not lock up when it get's hot. If mechanical is a shroud in place? If electric fan can it be turned on earlier? Or is it just lack of a big enough radiator?

Its an electric fan hooked to a toggle switch till my fan control is done. I did not turn the fan on In the log

Basically Mark was telling you to get the truck down to normal operating temperature. 228*F is TOO HOT! I do not like my small block to even get above 200, much less almost 230.

[lilhupper]

a little hot in both these logs going to put a 160 stat in tomorrow

[lilhupper]

here is one with a 160 stat.
