Convert to FBGI0

Unread postby ShadowDrake » Mon Sep 09, 2019 12:15 pm

Hey Decipha,

You got me started with FBGI0 a while ago but I couldn't get the car to start on the file you gave me. The injector data wasn't close, seemed like it was load scaled... but I couldn't get the car to fire like that no matter how much I changed stuff around. I DID finally manage to get it to idle by putting in non-scaled values for the injectors, MAF, etc. The MAF clipped up top but I was just trying to get the car to run. It would idle but I couldn't get it to work at even part throttle.

Since I'm so far out on that I'm asking for help.

I have, however, managed to get my FBFG2 tune running mostly acceptably. Startup is great every time at any temperature, transients could use a little bit of work, spark needs work, WOT fuel is too rich when IATs get high. I haven't made a full pull because I'm pretty certain I'm going to be out of injector. Changing the fuel pressure setting doesn't work. But I've got some dyno time coming up in the near future and I'm going to map out the timing.

That's all an aside, the basis of it: I have an FBFG2 tune that the car daily drives around on very nicely. I'd like to get it swapped over to FBGI0 so I can bump up the fuel pressure and get to something that's a little better supported.

The sheet is below and I can get some datalogs as needed, if needed. If you want some cash to help me get this converted over, let me know. I'm just at a loss on making FBGI0 work based on the file that you sent me before. My tune file has improved a little bit since, but I haven't had to do too much. It's not at the drive-it-and-abuse it stage yet. I just want to get it running with a higher base pressure so I have a chance at making the injectors work.

The last you got back to me on was here: viewtopic.php?f=18&t=3197&p=42205#p42161

But I figure it needs to be more official since I'm useless. The tune file is attached. Let me know what I should change that wasn't stated previously.

you have to scale your injectors regardless since the ecu cannot accept an injector slope value that high. Your fbfg2 tune has the injector clipped.

the only difference betwwen your fbfg2 tune and that fbgi0 tune i posted was that i had the maf slightly higher and the cranking pw twice as large on initial crank

I reduced both otherwise it should run well enough for you to dial it in.

make sure you download the latest fbgi0 in downloads and use the adx included with the fbgi0 xdf otherwise it won't log correctly.
