ya i think that would be good idea add 2 degrees and 2% fuel to 2 and 4, i may pull the plugs out and check like dex did.

Checked compression today came out 130 across!

here is a pic of 1100 miles spark plugs


4 3 2 1

4 and 2 should be the whitest by EGT readings! 4 Looks like its richest


Last thing i will do send the ID1000s to WitchHunter for flow check.

^^This!
I'd say something is just (very) off with your tune (waaayyy too rich) or your plugs are the wrong heat range.
Flow checking injectors is not gonna do much about either of those two. Especially since your compression is very nice.

If your that rich maybe bad mixture firing occures and you get more variation in individual EGT readings as well.
Also if spark plugs are the wrong heat range, getting in the right ones will probably also clean up your perceived variations in EGT's: if the plug doesn't fire cleanly, etc etc...

From your EGT reading, 350-400 Celcius is very low, suggesting also pig rich conditions coinciding with the plug reading.
I'd check tuning first. Whats your lambda target map where you ran these EGT readings?

it might be rich starting and rich fuel accel maps, because when i drive afr is spot on

You sure you have the O2 calibrated properly? That looks crazy rich!

That sort of thing happens on AEM widebands

My $.02 -- Bariga, you are using a partial set of consumer/enthusiast-grade hardware to attempt an OEM-grade tune. You need better measurement equipment. I would also not attempt what you're doing beyond a *very* minor per-cylinder adjustment without having complete in-cylinder pressure data at my disposal. You're relying on an incomplete analysis of the situation to make changes...but, you seem like the type of guy who will do whatever it takes, and in-cylinder pressure measurement tools can be had for sub $10k these days

wide band is calibrated and gauge and ecu show same number,

When the engine just fired what crank enrichment AFR i need to have?
Also how about fuel accel enrichment when i hit gas i think it goes rich as hell, because when you tap the throttle multiple times it chocking.

That kind of deposit is not going to happen from a brief rich condition on tip-in. Those plugs are showing a nearly constant rich condition and/or incomplete combustion. Maybe you're running too little ignition advance?

Whats your fuel table's unit? Is that IDC percentage or something?
I've only seen # milliseconds before..

Do you run closed loop? If so, what does your lambda target map looks like? That would tell more then a fuel table as each engine is different and all that.

What benefit do you see having the AFR Target as a function of MAP and ECT instead of as a function of MAP and RPM.

It looks like you're trying to handle you start-up enrichment via the AFR target table instead of with the post enrichment and warm up enrichment tables. Keep in mind that closed loop lambda may not be active during warm-up so you may not get any response tweaking your AFR target table until the conditions are met for close loop lambda.

+1 my afr target table isn't even active until ect is 70+ C

make sense, but any way you do this you will get same result.

You probably mean pre-crank prime. That only pulses the injectors once before the start for milliseconds. You won't flood anything out here.

Crank enrichment just adds a percentage of fuel for a predetermined amount of time during cranking.

Ok thanks, just don't like the idea of injectors open when key is on

What do you have in your injector timing table under fuel? degrees @ BTDC

Most ECM'S do that.

You keep saying you need a better tune, but you won't schedule a time and you keep ****ing with it.

Not to sound like a Dick, but you don't understand half the stuff these engines do.

For example, you said ecu and gauge read the same afr. Of course they do! Its the same output from the same sensor. They will always read the same if you have the 0_5v setup right.

Lots of advantages.
I can enable closed loop right after the sensor warms up. This means I can ensure that she doesn't run too rich when cold in lots of different conditions.
Pretty much all oem ecus do this.

Rpm has very little purpose on the afr target as load and coolant temp are the primary factors.

This is something we still need to work on. it looks like we are short circuiting the fuel.
