Thanks, Dave not using 10k jumper and wired as shown, belive I have a bad ecm ordered a replacement , reason being have issues with both circuts what are the chances of that??
Seems like this car...

Hey All, 7730 installed w/v6 mod memcal, had to change injector flow rate to 24 to get it to clear flood and run, the biggest issue is I a getting CTS & MAT Low errors they are connected to E16 & F...

Would you have a part number by chance.
Also if I use this I would connect directly to pin F9 with no resistor? Right

Thanks Dave, just purchased memcal, hopefully it will resolve some of my issues

Thanks Dave, this is what I was looking for,I just installed a 3.9 resistor on F9 to ground that pulled the 5vdc on f9 to 2.4vdc and code 43 is gone. Thanks again

I am using the moats adaptor and burt a base chip using $8D bin, the injectors are firing just won't run. It like the firing rate is off. Cyl select is set for 8

What won't work????

Thanks For the info, however I am having bigger issues with 7730 the car ran with 7747 ecm although not very well, with the 7730 I have spark, the injectors are firing but will not run.
as far as I...

Ok have the 7730 ecm with 7165 memcal installed, external est(knock) connected to b8, I am getting code 43 knock sensor failure, do I need to add 3.9 resistor to ground on pin f9?
Or move from b8...

ok. I did move injectors around and idle did improve quite a bit, still have tuning to do?? (still learning about that) keep in mind i am running a 7747 ECM. Until i can get my hands on a 7730 ECM....

Well, I am retired so I will swap them around over the next day or so and post the results

I'm at it again, Brain won't stop. Mabey someone has the answer.
GM uses batch firing of TPI injectors 1357,2468, the question is, why can't the injectors be batch fired 1843,6572?? which would be...

another question, you said connect knock sensor to B8, the pin out has it connected to F9. so am I to use B8 because I am not using a memcal specifically for the 7730????

Great thanks for the info, I will post the outcome when I get the 7730 installed.

Thanks everyone, I did get my old 7747 to run engine although not very well. i have read it is possible but would be better off moving to the 7730.
Forgive me but what is netress?, and to I need...

My 7165 ecm will not fire injectors, checked every thing i could, so thinking about moving to a 7730 . The question is will the memcal from the 7165 work in the 7730?
I am using the moates adaptor

Hey Dave W, thanks for everything,
But this conversion is driving me nuts, no mater where I set BPW the Idle is surging and high (1200), and in C/L the BLM is at 108 I have used the calculator for...

well i did the mechanical balancing of throttle bodies, I drove the car with BPW at 124 and it sneezed And coughed , set to 115 and no sneezing but backfiring out of exhaust(new).
I thought I had...

I did check into balancing throttle bodies and no I have not done that. I am curious if I can use the multiple vacuum gauges I have to do that

Thanks 1project2many, I am curious about the difference between 1227747 & 1227427?
The fuel pressure @13 has not been changed at least since I have owned it
as far as balancing throttle bodies,...

Thanks Dave, I did need to Change BPW to 120, I will get some logging done and post the results

Yes, using motes F&B and adaptor installed in 1227747

Well, its been a while, Life rules but I am back at the 84 crossfire, I did have to change ECM to 1227747 , still having Idle issues (really rich) starts out with low idle the as it warms up the rpm...

Hello from central Florida
I have an 84 vette with cross fire injection.
has been running super richich since I got it .
this is what i have done so far ,
hogged out intake, installed a summit...

Thanks, that was the problem, its up and running.+ still have super rich @ idle
