Looking for dead times for blitz 850cc injector any one have on or anything close to correct
-
search nippondenso 850cc rx7 secondary
search power enterprise 850cc injectors
search sard 850cc injectors
search titek 850cc injectors
all same injector i believe i found the dead times a few times with a quick search
assuming these are 850cc SIDE FEED injectors

Determine it empirically. It's not hard.

^^^ but time consuming ??? I found them their injector clinque injectors renamed

It takes less than four minutes, and it's not like published figures are remotely accurate. That shit changes depending on production lot, fuel pressure, how fucked up your charging and/or ground system is.
Have to do it means you have to do it, don't chump out on learning what the fuck is going on, and learning how to tune, just because some shit that doesn't mean what you think it does is printed out on a website somewhere. I'm retuning an R20 swapped 240Z right now because the asshole who tuned the previous motor thought 35 degrees timing was good for 15 psi, and this morning I dumped a tune off of a Lightning some other guy fucked up by hammering the base fuel table while leaving the MAF curve stock. This shit makes me livid - you DO NOT TOUCH SOMEONE ELSE'S CAR if you don't know exactly what you are doing.

I know how you feel. I went out to tune a car tonigjt and it had cracked ringlands do to a famous brad basemap. I tell all the locals I talk to that I'm not an asshole but I don't give out basemaps because thats how you tear shit up. I tuned this Brad guys car a few years ago and taught him how to burn chips I never should have done it. I lose a decent number of tunes because of that they get a price for a proper tune from me and then get a $20 basemap from Brad.
And seriously tuning battery offsets is simple. read pins D1=12v and d22= - with a multimeter get the car to idle at 14.7 or whatever afr it's smooth at. turn lights and stuff on and load it down then change the cells close to voltage your reading until it's at the original idle afr. you can unplug the alternator and let the battery run down and get the low voltages then to get high volts plug the alternator back in and then hook up a battery booster. it's not hard. I do this all this and tune ect compensation as the cars warming up. you have to get battery offsets first though or your afr's will get wild at different loads. all fuel mulitpliers in the ecu use the battery offset so get it close.

I usually unplug the alt let the bat die to set my tabels but this car I don't have much time to play with due to his fucked time frame and he refused to leave the car at the Dyno b/c his previous tuner.

Again, published figures aren't remotely accurate.
Simple solution is don't tune on unrealistic time frames.

Yeah pretty much thats about all you need to do usaully for common injectors like dsm 450's and such. But on some that Ive never seen before I take my time. Just explain to the guy that you need more time and make him understand you care about doing it right. They usaully understand. But sometimes if it's a stock gsr h22 swapped car I just burn the stock rom play with fuel for 30min then play with timing on some new plugs and get my pocket money.Again, published figures aren't remotely accurate.

Yup if the car owners rushing me I take it personally almost like an insult just explain that there are things you have to that take more time then the last tuner because your better then that guy. They usually fall in line and trust me when I put it like that. And were talking about honda software when is anything ever accurate. Ive been finding with crome that I can't burn a chip out of it because the afr doesn't match what I tuned with the ostrich for some reason. Using flash and burn makes it the same though.

Thanks for the tips guys will def use this in my future tunes.
