Ceddymods ROM flashed - now won't start

So I donated and downloaded the Ceddymods ROM/XML files for my Evo 6.5 Makinen - made the change to the XML file for the later 7203 CPU and flashed to my ECU.

Now the car won't start. Cranks, can smell lots of fuel, attempts to fire but floods before starting.

Checked a datalog while cranking and it's injecting large amounts of fuel (60ms!) erroneously.

Switch back to the factory ROM and it runs fine.

Any ideas what's going on here please?

Thanks in advance

have you loaded your fuel and ignition maps from original rom onto the ceddy rom?

Running the correct version for your application? MAF/MAP...

Try downloading the rom file again from where you got it from sounds like a corrupt file

Yes i've tried to start it on both the Ceddy ralliart maps and the fuel & Ign maps from my original ROM, no different unfortunately.

I'm still on MAF, but I can't see where there are different versions for MAF/MAP?

all good, thanks for the ideas guys, got it sorted. Was a flag in the setup that disabled all ceddy functions (ALS, launch control, SD etc) that for some reason was stopping the car from starting at all.

Never mind that, was being stupid and looking in the wrong places. 12 hours into a 16 hour night shift really plays with the brain lol
