G8 with FIC1000's. Injector table limit issue.

[glanzergtx]

Hey guys,

I have a buddy that put FIC 1000's in his LSA swapped g8 and im having a hell of a time getting fueling right. Can someone chime in and help me out.

I have attached the FIC data along with the tune.

Tyler RCR lsa 2-4 FIC1000 91octane Data Adjustment stoich .hpt

Here is the injector data.

Explain what you mean by getting it right.

When we go with a 40roll downshift the car will stay in the gear it downshifts too. I looking for someone that knows if i scaled everything right.

Stays in the gear? As in, all over the rev limiter until you let off, then it shifts?

[glanzergtx]

Correct

Use the bluecat trans tool to get your shift points right.

How many threads are there on the first page now that are complaining about not being able to get fueling right on FIC injectors..?

You got what you paid for.

the trans table isnt the issue. The trans shifted perfect before the injector swap. I believe it has to do with applied engine trq

Im not worried about the fueling. Im trying to narrow down what i missed thats not allowing the engine to hit max trq. I think i missed a table when i was scaling.

So the only thing you changed was injectors. You had to scale the data to make things fit. Now you have drivablity issues.

Conclusion - You did something wrong.

Suggestion - Start over, be more through. This isn't a problem with the injector data. A data problem would show up in your fueling. This is a problem with your scaling. Once you think your finished compare old scaled tune to new scaled tune. There should be a difference. If you can't find one, study more.

How insightful of you.

I try.

Your dropbox link is broken.

I have FIC1000 injectors in an LSA G8 also and your offsets are vastly different than mine. I'm interested to see the data you're using.

Looks like a return style fuel setup? Need to know your baseline pressure. Looks like AFR is scaled 66%?

IVT calculations need to be scaled, but not the TM reporting if you're using the AFR/IFR approach.

Interesting, this is the first I have heard of the IVT's needed scaled as well. Could you please elaborate??

I've never heard of IVT being scaled either.. especially when using the "double stoich / half IFR" method or similar

Thanks--that is very interesting. And something I missed in my own tune, thanks!

Awesome! Thank you.
