Icon5 B18b1 with P72 pistons tuning with crome

First off I have searched high and low on every forum and even tried for the last three weeks to get this engine away from running rich constant 10 after about 15 seconds of idling time and fuel cut or limp mode when ever I try to WOT. Yes it is turbo but no point in getting into all of that until I can get a solid basemap before this exhaust kills my eyes and leaves me with a permanent headache haha

So here is my list of mods.
P06 ECU
3 bar map sensor GM
550cc RC injectors
LS head and block all stock besides pistons and rods
Rods and pistons are P72
Turbo 50 trim

Using moats flash and burn with crome, do not have access to a emulator.

Thanks in advance to everyone

Hello. Have you tried a stock B16 basemap, setting scaled injectors to 550, disabling VTEC and setting the 3bar map sensor?

I have done a basemap for you, setting 550's injectors, 3bar GM map sensor,custom ignition retard per psi, disabled vtec.

Well, a basemap can't fry an ECU. If you don't know how to burn a chip, or how to tune a car, left it to a tuner.

Why you ECU is fried? Did you notice smoke? Is there any burned electronic component? Car simply doesn't start? Probably you have burned the bin code in the lower section of 27SF512 (you need to use the upper half, 008000).

I think I deserve an apology.

Yes Q31 caught a small flame, ecu top off laying in my floorboard so I definitely seen it and watched it smoke after it burned out. Once I get back home (coupler of hours) I will take a photo of it.

... U messed up some plugs on the engine harness that's why u blew the resistor and why start with a b16 map??? There are many good ls maps out there...

No I didn't mess up with any plugs. You told me you made that one for me to try.

Stop blaming everyone. Take charge of your actions!!!!

Q31 is a transistor who controls evap solenoid. You have a mess in your wiring, maps don't burn transistors.

He needs a start point, there is no better start point that a stock P30 map, for tune later.

Sorry but this definitely sounds like a user error and not the fault of any basemap!

Oh wait... can you even datalog?

Sounds like you should take this to a shop!

I apologize for freaking out, still haven't figured out the real cause but just to stop the madness I'll take the user blame for it. If I figure it out I'll post letting you guys know.

I bet you have plugs reversed on the EVAP and MAP or whatever two are alike back there behind the manifold, easy to do and many of us have done it! I can assure you a basemap will not fry anything in your ECU. I'd start by getting a new ECU, I'm betting its been bad all along..

I'm pretty sure that it is the IAT and EVAP, or the MAP. Ether way, the IAT circuit/transistor(Q31) is not set up to handle the voltage and it will melt. If left long enough the IAT sensor itself will be damaged as well.
