FIC 1100CC deadtime

[kchaazz]

Hello, everyone. Ive got the new fic 1100cc injectors, the plug and play, high z style. I have the data sheet that came with them, however, Im not sure how to gauge a good starting point for deadtime. Ive searched everywhere but it seems that very few have these injectors. Any suggestions? Perhaps the data sheet holds the answer?

Okay, i took a closer look at the sheet that came with the injectors and i think ive got it. IF I am correct, the sheet states that at 39 psi base pressure and 12 volts, deadtime should be at 1430 total, since 1 ms is 1000us. 2g would use the 43.5 psi table. Just multiply the ms x 1000 and thats your answer. I put those values in at every voltage. Now im not sure if we should be adding that to the stock values or if the numbers on the sheet should be the total because i had to add a bit of fuel with my maf comp table to get my low trim in check.

Use dsm wiki to get a starting point. It shows new info on the 1100 high z injectors.

Your math is correct! With a base fuel pressure of 39.0 your "InjBatteryAdj" settings should look like this.

8v=2980
10v=1950
12v=1430
14v=1160
16v=0.980
19v=0.980
I made the 19v value the same as the 16v, assuming that those values typically wont be used. (hopefully that is correct)

I didn't add those numbers to the existing values. It just didn't seem logical to.


Now its time to refer back to this guy...

Well, I actually use Tunerpro RT and an Ostrich to tune so my setup is slightly different but the principles are the same.
