1986 IROC with ZZ4 350

[ZEDRATED]

I hear u. I spent $600 and my car ran like crap. I'll call up John again and ask him.

Hi there gentlemen. I called and emailed Jon at FIC. Here is the numbers he gave me for the voltage offset corrections:

6 3.033
8 1.827
10 1.275
11 1.093
12 0.946
13 0.836
14 0.731
15 0.637

Soo????????

plug them numbers into your battery voltage injector offset table

I was just wondering what u guys think about these numbers? Do they look right?
I havemt looked at the bin file yet but what if the voltage numbers aren't the same as the ones I just posted? Have to do calculations?

Replace what is there with what he gave you.

Merry Christmas to all.

The wife just got me an emulator for Christmas. Wooooohoooooo.
Cant wait for spring to play around.
If she gives me shit for spending to much time on the car I can tell her that she is the one who bought me the emulator hahahahaha

That's the issue, it does not matter if they look right, none look right, they are all different and match the injector.

Sounds good thanks. Now I just need to wait for April/may to roll around :-(

plug them numbers into your battery voltage injector offset table

So I got curious last night and looked at the injector offset vs battery voltage table in the bin file and I would have to do some calculating with the numbers Jon at FIC gave me. What's the best way to calculate these numbers to make them work in the table?
I asked him if he had exact numbers to match my voltage numbers in the bin file but he said I would have to do the calculations.

are you sure your xdf is correct that looks like a wrongly defined table with "batt volts" instead of "Injector bias add-on vs Injector pulse width" all the codes i work with run a 8 colomn batt volts table and 17 colomn injector bias v's pulsewidth table

I'm pretty sure. Anyone else want to comment?

Here's two I found if someone has time to double check. I just don't have the time but wanted to help...

anyone???

I missed your thread earlier. I have had a 1-wire O2 stick rich at idle and it causes the AFR to go way lean. the car would run great any other time but go full lean at idle. I tested the sensor with a torch and it would first stick rich as it cooled down from it's working temperature. A 1-wire O2 just doesn't work well at the end of headers when it doesn't get enough heat applied to it.

As for your offsets. Extrapolate between points or draw a graph spread out on a big piece of graph paper to get the values for the voltages you need.

So disabling it might not be such a bad idea?
I managed to install a 3 wire one. Seems a lot better but still goes a little lean but didn't try tuning yet with it on. We'll see what happens in the spring.
