is it setting closed throttle mode?

does tprel read 0 at closed throttle ?

the tps is fine but the iac would need to be swapped

Attached very limited but usable if you have a base tune already.

debyma is set to 0.12 lbs that clips the minimum isc airmass to 28% duty cycle from the fn800 iscdc lookup

manifold volume is for tip in, you can throw that around to get her where she's happiest

changing sarchg requires extensive changes through out the tune as it changes load

maf didn't make any difference to the kam because the kam was referencing elsewhere in the adaptive table

yeah the ac clutch relay normally opened or normally closed is dependent upon your wiring harness.

03/04 cobra, GT, V6, Mach1 - not set == 0
99 cobra - set ==1

if its configured incorrectly then the ac clutch will engage while the ac is off and eventually pop off the prv and spew all its refrigerant or it'll burn up the compressor from being forced on if there's no refrigerant at all.

if you didnt copy over your pats code and it still ran and fired up then that would mean your original ecu was replaced at some point and the pats code was blank == FF and someone reprogrammed pats to that, thus your pats code is FF which is what you have in that tune.

But yeah you should definitely read out your tune off your ecu to copy over your vid block, pats code and vin.

its easy you just need to get all the baseline stuff situated first.

meth/water is no biggie you just spray

thata debyma clipping it

that desmaf correction is fine, after you have it all situated the isc multiplier table is where youll apply all idle air corrections

you need to enable emulation, change the value and hit the blue update icon that will only appear when your emulating

i think its listed in the getting started write up, if not LMK

8 is idle feedback min clip
9 is normal idle feedback

you corrupted the fn875 function

you need to disable iat2 the MCT_HP switch since you don't have a cobra with the iat2 You don't have a supercharger bypass nor a map sensor or intercooler pump either.

oss teeth count for 4r75w is 24.

you doubled engine size sarchg but yet didn't reduce the spark tables so you are severely over advanced. What saved your engine was that you didn't disabled iat2 so it was setting a fault and yanking 10 degrees out globally.

did you try reducing the flow at your idle maf counts by that .88 error ? You have idle corrections referencing a part throttle learned value in the adaptive table.

your idle is going to be highly unstable because you set the idle spark gain really high so minor inconsistencies are going to throw idle spark around significantly

on decel your fuel pressure is pegging out because your fuel pump voltage needs to be dialed in

changing prldsw to 2 uses pct_load, why did you do that?

You didn't copy any of the SP** parameters over from stock so all of your base values are more than doubled.

The mach1 has AC_RLY_IS_NC set to 0, you have it set to 1. That will force your ac clutch to be engaged when the ac is off.

You can't set knock sensors to 2 without enabling all the knock sensor stuff and setting sane values. The 03/04 cobras didn't come with knock sensors so it all needs to be populated.

You don't have your pats code in there??? How is it not setting a theft fault ?

With a single turbo you need to disable bank 2 hego.

This should make her significantly happier and give you a much better start.

mach and gt ecus are the same

are you using the mach manual cal?

10 years, 50k miles, or 100 passes

whichever comes first

the old kb kits leave a lot to be desired and are too small

youll want/need at least a 2.8 L blower minimum.
