I'm trying to convert my 88 SD to MAF with 24lbs, the part I haven't been able to figure out is the ecu conversion. Do i have to get a computer from a 89+ and flash it for 24lb, buy a brand new comp that's preflashed, try to find a used one from a cobra (fat chance in hell) or is there any way I can flash mine? Also where is a good place to get the rest of the garb to convert to MAF for 24lb?

you need a calibrated maf, or a tune. and you really should step up to 30# injectors

what heads and cam are you running on the motor??

Topher306

heads and cam are both stock, but heads are rebuilt. All faskets on the engine are new, the block is all machined, as are the valves. The lifters are all new too, and all the internals are forged. You say the MAF needs to be calibrated, so does that include the ECU or can I just get my stock on calibrated?

mjr46

so the bottom end is a 347 ?? anyway you can purchase calibrated maf's from places like c&l or pro-m

Topher306

Yup bottom end is a 347 stroker

Yeah, Step up on the injectors

Why would I need to go up to 30? And will that affect anything in terms of the MAF conversion?

AdderMk2

because the 347 will require more fuel than the 24#ers can flow. plus when you realize how bad the top end you have is... you will have enough fuel to support it

Top end being bad aka stock heads and cam and all that? Even being rebuild and with new hardware and such it'll be that much of a problem?
