I have a 408W combo that I'm just getting going in a 94 mustang. It's a 408, supervictor EFI intake, tfs-r heads, and 10.6:1 compression. No power adder. Using the 94 harness and T4M0 EEC.

I've installed 80# siemens injectors (just like the FMS ones but with an EV1 connector) and a SCT BA5000 slot maf in a 4" intake tube. I've also wired the IAT to the slot MAF instead of having an extra senors dangling around.

Using BE 2012 and a Moates QH, I've edit the T4M0 calibration to disable thermactor, EGR, adjust for CID, 80/80 injector slopes, and the MAF transfer curve for the Ba5000 in a 4" tube.

I've got it to start and set base timing. The check engine light is on so I pulled codes.

I'm getting codes 511, 565, 113, 157.

511/565 are memory test issues. I'm hoping this is because of the Moates, but I don't really know.

113/157 are complaining basically about voltages coming out of the slot MAF.

Has anyone used a slot MAF with CBAZA/T4M0 and had similar issues? I checked my pigtail wiring and I'm 99% sure it's right.

Any help would be most appreciated.

good luck tuning with the xls

best bet would be the full cbaza def, can do so much more, i don't even waste my time on the xls its lacking a bunch of stuff

I'm going to move over to sailbob's cbaza.cry as soon as I can get a hold of him.

Just as an FYI to everyone, sailorbob's cbaza.cry doesn't work the BE2012 according to him.

I switched back to 2010 and got the cbaza.cry. Talk about a lot more options!

I've even found settings for minimum maf voltage so I should be able to stop the code from being thrown.

can you tell me the proper wire color code to wire in my new 05+maf pigtail to include my iat sensor?

Well I don't know if it's correct yet, but I used this info to put it together:

search cgrey8 he made a post with details

Here's my thread:
Custom intake track for slot style MAF sensor

I read through that thread but I didn't think there was anything really speaking to the IAT?

Did I just miss it?

No. Just additional info about what pins in the slot style MAFs are the IAT.

What I don't know is if the IAT in the slot MAF has the same transfer as the stock IAT/ACT sensor used in the old 89-93 days. And it's not as simple as just updating the tune with the slot style IAT sensor's curve because in the old EECs, the ACT and ECT use the same transfer function. Thus they have to behave physically behave the same for those EECs.

most thermistors are identical from basically everything including automotive, refrigeration, aviation, the whole 9

even if there is a slight variance it wouldn't matter since you can put what ever value you want at what ever temp you want for timing retard

Interesting. In HVAC, they are not. We have Precon 10k thermistors categorized as Type II & Type III (slightly different curves but both 10k@70degF) then we have the less common 5k of at least 2 varieties, but I don't think they are categorized as "Types". Then we have 1k platinum, tin, silver, and nickel RTD transducers each which have different transfer curves.

But I agree, you figure out what the ACT value is it is reporting for the various weather conditions, and adjust your tune accordingly particularly if all Ford thermistors are at least similar.

Seems that VMP tuning thinks it works. I'm going to call them and ask about this setup..

the vmp 94-95 harness does not wire the iat sesor. i have it laying around.. i used the newer vmp 96+ and the a harness i had previosly spliced for a lightning maf.. i wired my iat but i didnt know it matter so i dont know which iat wire is which now..

That's odd. Their page specifically says this:

Our harness replaces your entire stock MAF/IAT harness and utilizes the IAT/ACT sensor that is built into 05+ MAF. This harnes will fit other Fords that use a round 8-pin connector for a *seperate* MAF/IAT harness assembly.

i tought the samething but if you look it says 94-95 v6

from there website
Replacement Harness Fits:
94-95 Mustang V8
94-04 Mustang V6 (allows the IAT to be used in the 05 MAF on 94-00 cars with seperate IAT).
97-04 F150 old style 4.2L, 4.6L, 5.4L
04-08 F150 new style 4.6L only (the 4.6 still uses the old tonsil style MAF)

hmm interesting, i always thought all thermistors kicked out the same resistance, i used to play with those little project breadboards radioshack used to carry when i was a little kid, i had like 8 different thermistors i collected with different designs and what not, no matter what they all ohm'd out the same at ambient temp

rtd's are metal core and are completely different from thermistors which are ceramic.

I also forget, in HVAC we measure temp in the decimal places. The Ford EEC measures temp in 2 degree increments. Now that I think about it a little, I doubt you'd recognize a difference in the various 10k thermistor types with that rough of a resolution.

A while ago I asked the same question about the AIT. And my research came up with the same transfer function. Should be plug and play.

well the one i have didnt have the cables for it.. guess i got a diffrent one.. ill post a pic of it

as you can see it oly has the four maf cables.. unless they offer another one which would of being nice to get i the first place.. i sent and email about when i first got it asking about it also asking for the maf trasnfer but never got a reply.

That is their universal harness. The one I was talking about is 94-95 specific and has a big round connector that goes into the body/computer harness.

This is the 94/95 specific one:

guess i got f*&^ed.. i have useless harness laying around.. oh well i got something going now.. but that would of worked alot better..

Have you tried wiring the stock sensor back in to see if the code goes away?

To me it sounds like you have the wires switched and your getting the source voltage in the signal wire and it's always reading max.

Verify that you have the wires correctly routed.

Turns out I had just a really bad connection. I tried to use some weatherpack connectors and it just didn't work out.

I got the VMP harness that plugs in to the 94/95 main harness and the slot MAF. All was well after that.

Thanks!
