I just put a new ecm in my truck and it cuts out under hard acceleration (not as bad as before) and when it does the check engine light comes on. I got a code of 31, but can't find what that means anywhere.
ECM code 31

It's overboosting. I guess you have a stock turbo. It can be caused by several things. Do you have a cat converter? A dirty air filter can cause this too. Check the vacum lines around the wastegate actuator (sits on the top of the turbo) too. Are they there?
What's your mods?

Click on maintenance then go down to the ALDL identification etc...
Get a SyTy CDRom from Opie.
Cold weather and a wastegate rod that is adjusted too tight can cause overboost problems, as can broken vacuum lines, stuck wastegate etc..
Have you had a chance to browse the SyTy faq?

for mods:
walbro fuel pump
taylor ignition wires
brand new cr42ts
MSD distributor
ultimate chip(not connected right now)
intercooler pump on with ignition
built tranny (higher stall convertor/race clutches etc.)
stock air box and crossover pipe removed (filter above battery which is relocated lower)
all hoses and vac lines under hood are new.
there is a vac leak in the dash when the heater controls are on i just found out yesterday. I will also check those lines by the wastegate...maybe when I was charging battery i bumped it.
the truck hasn't been driven for almost three months trying to find out what has been wrong with it. the plugs i put in in november were badly fouled (wouldn't even start with new computer) just from trying to start it and when it would run it was VERY rich. so I am sure the valves and pistons are a little carboned up and the cat is probably full of raw gas. i just got my laptop this morning so tomorrow i will have a look inside the computer.
thanks for the input. any more is welcome too.

well after just a moments inspection i found a broken elbow on the sensor that is between the turbo and the wastegate (sits right above the turbo) thank you guys very much for your help. I will find out tomorrow what's going to go wrong next. (still have to fix vac leak in dash--when heater controls are on)

Jamie if you are driving your Ty in the winter and want a hand or just to shoot the shit, please let me know. I am dying for my SyTy fix!!
PS: I really feel bad for not hooking up with you earlier, I know I said I would but never got around to it. Did the new ECM solve your ignition/distributor problem?
