Ideas for 4 cylinder MPFI = Toyota 22RE with GM ECM?

[EagleMark]

It does not look like the DIS is going to be hard at all. Just need the trigger wheel CAD drawing then cut out and mount a crank sensor.

Back to ECM it looks like 1992 2.0L and 2.2L went MPFI and already had DIS, so 92-93 era some were MPFI and some SFI, I think the MPFI will be fine and simplar. Just can't find what ECM and mask these are running yet. JY around here are full of this era cars for starting pint of harness, ECM, DIS etc...

Seems like the Quad 4 and other 2.2L 94-95 are supported, but are these SFI and need cam signal as well? Just seem to be missing the boat here on simple...

Mark,
I have a 1228708 bench test setup http://www.gearhead-efi.com/Fuel-Inj...ECM-8B-for-TBI

I could get crank trigger / sensor made that would bolt to the distributor gear, similar to the '0411 set up I built.

As far as CAD for the Quad 4 crank trigger wheel, I have that done!

why move to an unknown ECM? stick with what you know. since this is being used on something that won't have any type of factory calibration, any mask that is well defined and you're comfortable working with is a good starting place.

I figured you'd make one if I needed it.

Just can't find the mask ID of "1992-93 2.0L and 2.2L went MPFI and already had DIS non SFI"? Not on the TunerPro XDF and ADX lookup or TunerCat website. Just a car no one ever wanted to tune? Without a mask or dissasembly it's just to much work so I'm kind of still wondering where the beginning is?

May be as simple as a V6 ECM mask and changing cylinders and using the four cylinder DIS!

The DIS part seems to easy to use a distributor. Or make the distributor the signal for Cam/SFI? You know we did this once before and a four cylinder GM distributor had one, but was still distributor...

It'll come together...

I really don't mind another new one. It'll be something here I can always work on an improve.

You know the V6 area, what would be a good starting point to switch to I4, DIS does not seem to be the issue. I'd rather not start with a TBI DIS system which seems to be available...

But then again don't want to go MAF either.

if sticking with an underhood type unit, any 7727/7730 mask would work just fine. very few of them were TBI. you could use 8D if you wanted to. anything can b adapted to DIS pretty easily. the same cannot be said of switching between multi-port and TBI(especially dual-injector TBI) with the same mask.

May have found the CAD drawing along with the DIS wiring Robert has posted.

That looks too easy....

I would say weld/machine the plenum for a TB off an Ecotec or any later model I4/V6. No wait I would suggest just swap in an Ecotec 2.2!

I would really like to tell you to hit me up when need some machining/welding done on the manifold, but I think my Mill and Lathe are going to be removed from the shop by the middle of July in preparation for concrete. Should have them back in by September though.

Then that just opens the door to LOADS!

What about wiring from 6 to 4 injectors?

I've been ruling out 94-95 as they are SFI... but not sure they are with your new thread and files?

Those are flash right? There's something I don't have yet...

You've got a dissasembly for $6D so that seems like a good option.

with multi-port, won't matter as long as they're higher impedance, or at least are resistored up to high impedance. i wouldn't try to pull more than 8 amps through one driver, since that's what the TPI 305/350s did. so with 4 cylinders/injectors, that's a minimum impedance of 6 ohms per injector. any lower than that and they'll pull excessive current, possibly enough to damage the driver. for sake of simplicity, i wouldn't try peak/hold.

[EagleMark]

Looks like you have a lot of work and dissembly for $A1... has auto and manul paremeters so that's a bomus as truck is a manual...

Come on Robert pick a mask now that we are at 1227730-27?

The 16149396 is same?

I may go next week to JY and find a donor...

i would NOT recommend trying to get the P66 V6 PCM to work with a 4 cylinder.... it's plenty capable, but it's not happy at all trying to run in "non-SFI" mode, since it attempts to guess the correct firing cylinder when the cam pulse isn't present.

even if the cam pulse were present on a 4 cylinder, it still seems like it would be more trouble than it's worth.

6D would work fine, i mean it's pretty well defined, i didn't want to put a ton of time into it, so some EGR and EGR diagnostic stuff got left out. $88 is ~100%, A1 is ~100%, DF is ~100%, 8F has some quirks...

find one you like, run with it. all of the 7727/7730 60V6 stuff is going to be very similar in operation. 46->55->6D->88->A1->DF. 8F is a subset of 6D, but that's how they came out. 46 and 55 were MAF, 6D and onwards were speed-density(with 8F being 2BAR). DF needs to be in a 9396 since it allocates the stack in the extended RAM.

you won't NEED a 9396 unless you start playing with custom code(or run $DF). if you find one, go ahead and use it, they're usually a little newer than the average 7727.
