Does anyone have any input on setting up a calibration for an MAF conversion for a 460 (long term engine plans are .040 over with a mild cam) E4OD combination. I will be using a WAY1 EEC from a 5.0L Bronco w/E4OD. The MAF is from a 1995 Lincoln Continental 4.6L DOHC which a number of rebuilders list as the same as a CA spec 95-97 460.
I do know about changing the injector firing order, turning off some of the non-existent hardware and sensors. What I need some help with in getting a starting point is: MAF transfer, spark advance and transmission shift points, the 460 isn't really going to need or like to rev like a 302. I also want to try to keep the lockup engaged at highway speeds until just short of downshift due to the E4OD penchant for heat build up from the torque converter.
Thanks,

I just got my Tweecer today so I am starting to research things. Have you tried asking the Yahoo newsgroup this question? That group seems to be pretty active and knowledgeable.

With the engine displacement and injector values updated and with an accurate MAF transfer function you should be good to go. Yes the firing order has to be correct too but I wouldn't worry about ignition advance it'll be close enough for the motor to run and make good power. Note.. there are places that will measure your meter for you and generate a transfer file, I don't know who specifically but as usual when in doubt.. hit the web.

I have asked the Yahoo TwEECer group. Most of those guys are into Mustangs. I haven't found a good source for the MAF transfer, but do have the tables from Ford for the voltage vs. lb./min. gm./sec. if there is a way to generate a transfer table from that.
