boosted k20

Anyone got any battery offset voltages for 1000cc injectors. i got my car running fairly decent after tuning the offsets in crome. i wasnt able to datalog the voltages i was seeing cuz my laptop with cromepro got fried, so i borrowed a friends laptop with crome free. i wanna compare my values with yours, cuz im still getting a slight problem with the fan comes on.

I do not use datalogging to set the battery offset. Grab a multi meter and use A25 and A26.

Plus, different injector makes (and styles) will have different offsets.

Use the battery tables with the latest version of Fuel Tools, and THEN use the Offset to bring it into check.

All you are doing by adding to the Offset is increasing the battery offset tables to that number.

35 offset = adding .35 to the battery tables.

BTW, the battery tables in Fuel Tools 2 (ver 5 or whatever) are just the tables copied over from AEM's tables. They work, but they all seem to be low IMO.

i couldnt notice a difference when i used it...

Batt.(volts) 19.5 14.9 13.9 12.8 11.7 10.6 6.3
Inj.(ms) 0.32 0.33 0.47 0.75 1.24 2.10 2.05

This is with precision 1000cc injectors, stock resistor box, and with fuel tools offset set to 48. The afr stays steady when the power windows are operated at the same time and everything. Occasionally there is a slight dip in afr if the fan turns on and the stereo is booming, but overall it is setup very well.

the fuel tools offset that u put to 48, thats under the "Fuel multiplier"-"advanced" and u set it to 48?

Yes, exactly. The whole map was tuned with that offset.

okay i'll try that.... and its 48 not 0.48 right?

48.0

boosted k20

when i first did the basemap, i had left it at 0.00 and i tuned the fuel out like that. if i put an offset of 48 it will run pretty bad... But since i have the fuel maps tuned already with ti set to 0.00 i guess it should be okay.

but i did alot of tuning last night and the car is running pretty good. no more stalling out. i had to adjust the IAT to get it running good. my battery offset tables are lower than yours though. from 12.8 to 10.6 volts, i have the offset at around .7-.8.

thanks for the help
