If he just tuned it on the dyno for a break in tune, he may not have had time to adjust all of the warmup and startup settings to his liking.

We changed compression ratio and rod length for starters. And we never finished the last tune, remember? You were having boost control issues and we put off finishing the tune until you got them squared away.

Bariga,
Maybe a long shot (or a short one), but couldn;t you just try a warmer plug for starters?
Spark plugs are cheap after all and an easy/fast swap.

Rod length is same, we went with long rods remember? And compression changed to 8.5 from 8.2 or something like that. Ill call you tomorrow to see if you have time some.

It isn't really anything. It's like VE, but not exactly. If you change the master fuel, then it changes total fuel by a percentage, which then means you need bigger or lower numbers in that table. I can set it to be 55% at idle and make it approximately match VE, but it doesn't matter.

I've asked multiple times while tuning this car "Are you sure the WBO2 is calibrated properly?"

Judging by the EGTs and rich plugs I'm not so certain. I'm going to check the end of injection point and see if we're short circuiting the fuel.

One thing to point out is that Bariga lugs this engine alot. By a lot, I mean A LOT. He shifts very early and just putts around on it less than 2k rpm everywhere. He doesn't accelerate with any zest. He thinks he's doing the engine a favor, but I don't agree.

I think what needs to happen is this:
1. New WBO2. LC1 at a minimum. Or at least let me verify the readings with my AFX WBO2. If the plugs are that dirty, the sensor is probably that dirty.
2. New plugs.
3. Let me finish the tune.

He got the boost control system working fine so let's do it.

Tnx Maxwell for the interesting read on the fuel table numbers!

I'am sure between the two of you, you'll sort the engine out till its ~perfect!

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.
Its in percentage of the overall fuel master value. If you overall fuel master is 16.35ms a value of 100 in that cell would net you a 16.35ms pulse width.

The last two AEM WBO2's in my car have proven to be worthless except for quick visual checks that fueling is half-way sane. Not nearly accurate enough for precise tuning.

did you change the master fuel on accident? It was 12.5:1 according to your wbo2 at 7psi.

No bro, the only places i mess with is idle and cold starts

I noticed gauge read out is .2 / .3 different from what ECU shows! I tipple check Cal settings for it with manual and its correct.

most of my standalone customers use LC1 and not the AEM, so I haven't had that much time with it.

Voltage offset from different ground. You have to manually correct until they read the same. Or make sure sensor ground is same as ecu ground.

Also thought you said before that you were 100% sure it read the same...

This is the easiest fix, ground them all at the same physical location, same ground lug.

Yes and one of the 4 leads that come from it is an ECU sensor ground. Your LC-1 and gauge should both be connected to the lead that is the ground lead. Are they?
