Tuning cant come soon enough...

[ZXMustang]

I was out "breaking in" my new 25 GT. Watching the AFR for several WOT pulls on the highway. And it consistently goes 10.0 rich at the top of 3rd and all the way into 4th (10R80). That's very rich.

My guess based on the gen 3 calibration is that its commanding .70 lambda for CAT enrichment. And no matter if i do the pulls when the car is cooler or when its completely heat soaked, I'm seeing this same behavior.

I did swap to e30 now and it feels more consistent but still going into cat enrichment. But it still needs to be gone through. I can limit the level of cat enrichment to something way more reasonable than 10.0, like we do on the gen 3 cars with cars. I wont get into specifics. But once we get tuning - (i'm hearing industry rumors), its GAME ON. I'm going to work over the fueling, push the spark a bit and set up the mother of all trans tunes like I did with the gen 3.

Cant wait for this to be tunable. It needs it bad.

Can you actually data log it? Wonder if the dash is just slow to update

There is a small amount of PIDs available including spark advance and WB EQs so you can see real spark and lambda. But I can’t see any KR or anything Trans.

After taking a spin in my 2024 today, I feel a 500 rwhp would make this thing dang near perfect for me.

I know the Gen 3's can get there. Wishing, wishing, . . . . . .

They definitely need tuning, an extra 20-30whp would do wonders for this car along with trans tuning.

Trans tuning = Tremec

Doubt you're going to get any power out of a tune, they're so agressive as it is.

Steeda's car only made 450whp with headers and E30, not sure if they had slicks on it though - that would suck some power. They also had some lightweight wheels/driveshaft so it seems like it should have made more but I'm not sure what gear they were in either.

There's tons on the table man. Reducing Tq management alone is going to be a winner. Adding a few degrees of spark and adding a tad more fuel. Reducing COT and trans will be killer. Mine will be banging shifts at 7800 like a swiss watch. Revise the TCC too. You have no idea whats on the table here, and we are going to get it all. Cant freakin wait.

Still not going to get 30hp out of it.
