injector info? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Does anyone know the injector info on the FAST injectors? Like Injector flow rate at 58psi, injector voltage offsets, short pulse adder, minimum injector pulse width, etc.

FAST often does not have injector data. We do not use them for that very reason.

There are a lot of tuners that use FAST injectors and there are a lot that don't lol. I for one will be putting FAST 85lb injectors in mine when I do my cam swap.

How does that help get the required injector data?

It doesn't. I misunderstood the your post and thought you were wondering what size injectors to get...

FIC is another popular brand to look at if you decide not to go with FAST.

We have FAST, our tuner needs the injector info. We got them before telling him which ones we were getting because we heard good things about them.... but now we have to get the injector info before he will tune it because he says they are hard to tune without the info.

I gave up on them when I had to go to larger injectors, Comp Cams/FAST tech support told me they have no data for their injectors. It cost more, but I went with ID.

Bo White · 12-29-2013, 04:46 AM

A lot more. My tuner doesn't even flinch at the words FAST injectors. He was the one that reassured me they are good injectors and that he's tuned them in a wide variety of GM vehicles.

A lot of tuners just plug in the size and go. You may never know what your missing but I've seen people swap to IDs and be amazed at how much better the car drives around town. WOT typically isn't an issue but part throttle, idle, tip in, etc are much better with correct info.

Bo White · 12-29-2013, 10:13 AM

Im sure tuning with info is easier but like my tuner said you still have to do tweaking in each individual cell on the map. Its just being thorough on the tune that makes the difference on not having data with the injectors.

Iam Broke · 12-29-2013, 10:18 AM

FIC provides data, it's kinda close. ID data is very close. Easy to dial in.

I disagree. Either way you should hit all the cells but is he varying voltage on the car to adjust fueling from 11-15V? Without the data fuel could be spot on at 14V and off at 13V. That is why there is voltage offset data. Things like that don't matter if he tunes every cell.
