Looking to transform friend Mustang to run off 7730, All seems like it should be easy excepy for DIS signal.. Will this be same as
GM output signal?

I have been telling him of the benifits of self prom tuning and ease of the 7730, better resolution vs a DFI. as well as multiple outputs that can be used.
Would like to tackle this for winter if do able...

I think I remember Grumpy mentioning this before..

Some info about car:
Stock 302 shortblock 9.5:1, Ported Trickflow heads and intake, 232/236 HYD roller 110 lsa. Pro shifted tremec, 456 gears.
3150 w/driver
Best et 11.36 @ 117 with 1.50 60.

Just dyno car made 340 @ 5900, pretty flat A/F car liked leaner mixture about 13.5..

 

I'm going to be swapping a v6 ford ranger and dodge omni to a 730 ECM. My research indicates that you can use the ford distributor's pickup coil to trigger a GM module. Just make sure the polarity is correct. I think you might run into other issues(like the IAC)..

 

Aside from the ECM issues...I know that BBK or some such company makes an adapter to use a GM 4-square pin IAC on a 5.0 HO intake.

 

I don't really fear the IAC, it can be run remotely if need be - or not at all. I run my car with mostly 0 IAC counts sometime single digits. With exception of throttle follower.

 

It gets quite cold here in missouri. Cold starting is an issue for me. Unless you want to hold the accelerator down untill the engine is warm, use an IAC. Yeah, you really don't need it but it'll make a smoother running motor. My guess is that your T/A's IAC is not working correctly OR the passage needs ported....

Please keep us updated on this project!

 

The IAC works fine, I just keep throttle blades open enough that I use little IAC as possible. Thats a Grumpy recomendation, seems to better throttle response.
Temp gets really cold here as well, cold starts have never been a problem.

I am looking to find out what I need to do to make this work. I am sure there are some people here that know.

 

There were a few Stangs in the Bay area running 749s, years ago. I'm pretty sure all they did was wire the FoMoCo reluctor to the GM module.


I'm to the stage of the max IAC value now is 26 in my GN tuning. I probably could run 0, with no noticeable change.

FWIW, my beater, is EFI'd, and has no IAC at all.

 

Why dont you then?

 

It gives me something to watch on the Scanmaster as it cycles down during a start-up.

I just might use it to help clean up the emissions on a sudden throttle lift thou.

 

... I wasn't trying to say that the IAC is THE only way. It can be very beneficial to have, that is my point. Other than that, I have a problem using a ford TPS. BUT all Tom really needs to do is hook up the dist just like I said. Gotta love Fords w/ GM electronics.

 

I like no IAC but sometimes I do like it. It's nice having the ability to deside on the fly when you want it and when you don't. Thanks craig for that 8 in 1 adaptor.
The other reason I like IAC is cranking. TBI's don't like to fire up and stay running when the IAC isn't there or is completely closed and disabled.

I'm curious, why, if this guy's car is running so well with the EEC-IV, does he or you want to go to a 730? Is it to ditch the MAF or is it for boost?

 

Don't forget about the ability to change idle speed w/o any mechanical changes, that can be nice to have....

 

Yes, if you've got a/c, power steering, big electric fan etc. you would probably want the IAC to make their on/off states undetectable.

 

For great driveability, ease of tuning, better resolution than a DFI, and much cheaper, ability to change injectors without MAF change, good support from TGO members..
Car runs great and drives ok, On the dyno there are some Lean spots, the only means of tuning he has now is an RPM extender that allows Global A/F changes. Also hunt for idle some. ect, ect, ect.
Not a boosted application, car is N/A.

 

I did this a while back on a 93 F-150, using the 7727 due to it's ease of underhood mounting. I just snipped the wiring at the underhood 60 pin EECIV connector and attached GM terminals to the existing wiring.

Here's my parts list from the swap:
Ignition Module ACD D1961A
Idle Air Control ACD 217-419
Coolant temp sensor GM 15326386
MAP sensor GM 12569240
MAT sensor ACD 213-190
Oil press switch MA 273541M91
Distributor MSD 8598

If you use the old Duraspark II distributor, it will talk to the GM module (this is what I'm using in my IH pickup w/7747), however Ford changed the size of the distributor housing somewhere in the 90's and that distributor wouldn't fit, so I just used the MSD distributor. The Ford TPS works fine. For the IAC, I just used part of a 3.1MPFI IAC housing and built a little plate to bolt it to. The oil pressure switch is used just like the GM units and is "T"d into the block with the gauge sending unit. btw that is a Massey Ferguson (as in the tractor) part number.

 

Thanks alot for the great info!
I knew someone here has done it.
