is there injector timing under FUEL ?

there is a latency value........... but the cable acts like a dongle, and it's with the race car, so I can't access the program ATM.

there's that... it says min effective inj PW is 2.45ms, that doesn't seem right at all... confirm ?

2.46 ms is the minimum time the injector can be commanded open and it'll actually open........ like resolution??

Those pics are from an OLD version of the program....... the new version has a latency tool to calculate "lag" time vs system voltage and it doesn't leave it in HEX

any new shots anybody can provide ? 2.46ms seems WAAAAY too high for opening time for an injector.

it's certainly not resolution, commandable injector resolution is usually in the .001ms range.

I won't be able to get the cable until Sunday

Is Uprev going to do this for '02-'03? It has been a pain in the balls with my car....Now I have 720cc injectors, running E85 and revving to 7500+. These injectors are too big on 9lbs of boost. I can turn up the boost, but I'm afraid this motor is going to detonate soon. I don't think anyone has revved the QR this high consistently. Mine just keeps taking it....but who know for how long. It's not making the power it should too, because it's so rich up top. The SAFC NEO works for now, but I'd like something better.

Has anyone tried using launch control via map switching? I saw mention of this on the 350z forum. Just wondering if it will work for us too.

One of the 5 maps is a "Valet" map with a 3000 rpm rev limit. You can change this rev limit to the number you want to launch at. Go into this map as you stage then change to your "race" map, but don't let go of the CC-Cancel button until you launch. Rev the car to the pre-set limit, launch at your light and let go of the button. As soon as you release the button you are in "race" mode. Voilla, a 2-step launch!

As far as I know 02-03's are not supported and won't be for a good amount of time if ever, the only choice you have is to go stand alone

any cranking pulsewidth maps VS temperature ?

there is a cold start enrichment that is a % of base...... so when it's cold, like 150% of base......... which is why on a car w/ big injectors and no cold start correction, it will stumble for 2-3 seconds.

naturally.

can you please post a screenshot of this along with any other temperature-related correction tables there are ?

do you have to hooked up to the ecu to look at the files. i have my rom file. havent flashed the ecu yet. but i like to just look at the program. dosent look like i can!?!!?

You don't need to be hooked up to the ECU to read or edit the ROM file but you do need to connect your cable to the computer. The cable has all the license information that allows the user to use the programs he purchased.

Ah cool thanks man
