Thread: STI Injector Tune using Calum r.t

Good Luck!

Maybe you need to work on the VQ table.

I don't think messing with the latency should affect wot either. Mine doesn't.

What fuel pressure are you running?

On another note, I found that I had a small vacuum leak around one of my injectors when I put the O2 induction manifold on, so once I fixed that, it started running richer, so I had to change the K back down to 385 I think, but I left the latency at .84, and it's running great, probably better than ever before. So if you are running the tune I sent you with the higher K value, it's probably going to run rich. Did both run rich for you?

I didn't try the second one. the first one was 10-11's at idle and i messed with it to get it right but its still running lean on shifts on cold starts. same effect runs fine when warmed up.

And I was 4bar but I changed it to 3 bar for your tune.

When you were adjusting the Kvalue did you turn off the 02 sensor or set the flagged area to 0? to set the a/f at 14.7 @ idle? The latency of the Sti injectors seem to be very close to the stock nissan's. I think the stocks are .75 and the STi's are .76. Might just be the adjustment of the Kvalue and the tp min-max.

That's weird, I wonder why it's different for your car. I don't know what I did, but mine acts fine now between shifts, even when cold. I'm either really lucky, or did something that I'm unaware of, but it's running good now. You have a Z32 maf right? I'm just trying to think of anything that might be different between setups. I'm runnin a Z32 maf blow-through, the STI injectors @ 3bar, S4 cams, 9.5:1 DE motor, timing @ 15*. Anything different with your setup?

its probably the cams at the idle parts. I had to change the timing map to det. Silver can you send me your new tune. I'll try it out and see what happens.

And yeah I had the 02 off. I read .75 for latency on sti's on the 370cc injectors the bin says .64 for latency. My tune that worked a bit better then all others was latency of .73 Maybe I need to try and go lower?

It's suppose to be a little bigger because it's a larger injector and needs more time to open and close. Send me your bin.

E-mail sent with current .bin I'm running.

Got the new bin will try out tomorrow.

Blue whats your email? i'll send you my 4bar one that was working half decent.

I also changed my plugs because on my tune at WOT it would like cut out half way through almost like a back fire at wide open. That stopped so maybe it was to rich and just loading up fuel. but weird thing is the tips were white. Doesnt that mean lean? They also had an orangeish color on the porcelin right about the nut part of the plug? Any ideas?
