Need to know what inj. constant, i think it would be 143, how close am I? Can I erase the stock chip and reprogram it with ANLU.bin cop chip in the 8746 puter? I'll be using the inj, out of the cop car (68# p/h). It has a 454 T/B, ZZ4 cam.

Grumpy- Glenn ?

Thanks

Grumpy

If the cop car your talking about ran a 8746 then OK. You can't switch wproms from different computers in the C3 series of ecms. They have some code hardwired into the PCB.

I work a little backwards on injector constants, I play with them till I get close to 128s, and then tinker with the tables.

You might need BBC PU injecotrs for that much motor.

I suspect 143 will be quite rich (read pig) at idle and off idle.

With 65# units on a 350 setting BPW around 120ish works. Idle fueling had to be trimmed down. Higher loads were closer. YMMV....

Yes Grumpy, the computer and the chip came from the same car '89 Caprice Police car.

Can I assume it is a 2732A or can you tell me what it is. Or what chip # it takes. I might need some extras.

Thanks,

i am running a 383tbi c/w 454tb and 80lb/hr injectors at 120bpw.

What am I doing wrong, I can't get the 2732A to program using the windows or dos pocket programmer, it fails as soon as it starts and says device did not program.
Trying to load ANLU.bin.

So what gives, is anybody having trouble programming the 2732A chips on the Pocket Programmer?

I'm really stuck on this one-Help ! ! ! !

zippy

i had that problem until i looked up the number listed for my chip. i tried the same thing and found mine was a 2732 and not a 2732a. according to the listing i found, the caprice chip was a 2732 which lists as 25v and camaro's 2732a as 21v. donno if that is the reason, but just something i ran into yesterday.

Found the problem, the ribbon on the programmer is bad.

Don I'm glad to see you getting your engine going. I started with the same 89 setup as you are, but the injectors that were supposed to be 65's were 55's according to the color chart and the combo ran lean under accel. I changed to 65lb Holley's and it ran much better with a very good idle. I also had a problem at first with my pocketprogrammer for some reason it would not burn the chips that I was useing completly without burning over sereral times and once or twice trying the voltage at 25 and after that they seem to be working better. I too am trying to tune BPW for an overall base to start with. Idle is pretty rich . Let us know how the tuning is going.

I borrowed a P.Programmer and now I am able to start burning, using a formula (forgot where I got it now) using the 383+67# inj. the BPW ended up being 139. With that I went to VE table #1 and moved the coluums (20kpa to the 30-30 to the 40-40 to the 50 etc.)fired it up and have INT & BLM's at 128-129 at idle (35kpa) talk about lucking out on first attempt. I will take it out and drive it on Thursday and see where it goes from there.

Well, I took it out and drove it and it is acting strange, when I hook the Diacom to it the idle goes up to 1500.

Any thoughts here? Is this going to cause me problems?
Also when I set the IAC and idle to 600, it slowly creeps up to 900-1000 without the Diacom.

My guess is that the scan tool is in diagnostic mode. Set it to normal mode and it should be fine.

Some aldl modes do funny stuff like fix the timing and idle.

FastBroker

The Snap-On does the same thing. In DIAG (I think) it raises idle and does a couple of other weird things to other operatorsas tests... ie, cannot get good BLM/INT/etc numbers in that mode!!!

Get into the ROAD TEST mode and you're good. The engine will act as without the diag tool in that mode...

Thanks, guys with the scanner in road mode now I'm good to go.
