EECIV VS OBDII
I have a question about MAF in 95-96 trucks. Do later EECIV systems use a MAF like OBDII? I know 95 was a transition year as later models had OBDII in them I am just asking because I have a 1997 F350 with no MAF so OBDI and would like to convert it to MAF and not have to add the port for OBDII so did some systems retain the old port and SPOUT but also use a MAF sensor?

Ford makes a conversion kit to put MAF on some of the old systems. I don't think MAF means OBDII necessarily, though I don't know exactly when and what EECIV vehicles got the MAF from the factory.

If you have questions specific to YOUR truck, you need to also tell us what engine it has and if it's a CA or a 49-state model. There are differences.

PCM Questions
I installed a 1995 4.9l in a 1997 F350 there are 4 possible PCM's available not including the California one which I do not live in Cali so forget that one. Is there someone who knows the differences between them by their code numbers? I will list them for reference, my truck has the 4.9l and the E4OD tranny, EECIV diagnostics. I do not have an original PCM for reference which is why I am trying to decode the differences in these PCM's if possible. These are F150 PCM's but it makes no difference as long as it is for EECIV a 4.9l and E4OD tranny.
My orignal post here was about AFTER I get the truck running I would like to upgrade if possible to MAF but keep the EECIV and that is why I asked about the possibility of a 4.9l using MAF with EECIV diagnostics BEFORE the switch to OBDII in 1996. So two questions going on here revolving around the same set up.
1995 PCM numbers are-
F5TF-12A650-BAA
-BAC
-BBA
-BBC
Does anyone know what the differences are between these PCM's? They are all for a 1995 4.9l with E4OD transmission.
Thanks, Brian

I was doing research on another vehicle computer, and in that instance the last three letters where running update changes during the vehicle production run. I think I found this out on one of the EECIV sites. There are forums out there where people dive into this thing in a serious way, figuring out the software and the programming. It can get complicated.
As long as any of them will run your setup, use it. I would not assume a 1995 f150 with a 4.9 and a e4OD would be programmed the same as a f250 with a 4.9 and a e4OD, but in reality you probably would not know the difference. The heavier trucks had less emissions requirements, so sometimes that made a difference as was mentioned by a previous poster.
