$58 code in '727 ECM???
So, correct me if I am wrong, but if you can run the $58 code in a '7730 computer, you can run it an the '7727 also? Obviously, you have to wire the car correctly for the pinouts on the '7727 ECM, with the corosponding changes to run the $58 code.
Also, in my four cylinder application, can the '7727 fire 4 low resistance (2.2 ohms) without any problems like the '7749 can.
I was going to use the '7749 ECM in my project, but it would be a royal pain to run the wires inside the truck and not make it look hack, so the '7727 would make my life much simpler!
Any help is appreciated with this!!!

Wire the injectors up like they do in the Sunbird applications, rather then as they do with the Syclone. The Sunbird used 4 port P+H injectors.

So basically, still use the inector jumpers like the '7749 computer in the sunbirds use??????
Thanks in advance

Will it run 4 port P/H off one driver? I bet will it need upgraded (basically one half of the 749 upgrade..
Then wire it like a Sunbird but instead of two driver circuits with two injectors each, have one circuit with four injectors.

YOUR RIGHT!.
Dang.
No, while some have gotten by with running 6 P+Hs at least for a while, 8 or 4 per driver will kill the injector driver. Low DC like around town aren't the problem, it's continued WOT that gets to the ones I've killed on the ecm bench.
Thou, I wonder if one could add the additional driver, sensing resistor, and whatever else that might be missing?.

Well think about this.. Why not just do the FET upgrade, reduce the sense resistor by half, and run all 4 injectors off one driver, since it's basically one half of my setup.

Thinking, thinking, thinking, thinking.
Ya, OK, that'd work.
Now my head hurts...........
You should have dropped by, did lots of testing in the GN today. AND, the passenger seat was usually empty, most of the time. Just Doc riding shotgun, once inna while no ecm on the seat.....

As far as I know, the Quad 4 used 4 low impedance injectors, and the Quad 4 code has support for higher RPMs. The bad news is that there are probably no hacs for any of the Quad 4 code.

your right the quad 4 has ph inj. but as you also said there is no hack that I have ever found. I see you live close to me if you go to the yard you can get a 749 ecm cheap (3d or como) tell them you have a 88 quad 4 olds. double check the number before you pay. (89-91) use the other ecm (3d might lt you take the whole harness too)

Thanks for all the help that was given, I am glad to see that everyone is open minded when it comes to "non GM vehicle" questions!!!
