Thread: STI Injector Tune using Calum r.t

.84 latency 300 k value. I drove it cold no more falling on its face. But I did notice when I hit the gas it does Lean as soon as the gas pedal is touched then to the rich side. Kinda weird. It's like an instant thing happening then instant rich or whatever throttle I'm at.

Ok so some problems still. It doesnt fall on its face cold but goes lean like 17s between cold shifts. Warm it's all over the place in between shifts. And still I press the gas goes lean then to the normal a.f. Then when it hits boost it's super rich which could be in the tune.

Silver200- You said you have a tune for these, are you having any problems like I'm having.

I just checked mine.

Latency = .68ms
k value = 34182
inj volt adj= 102

Im gonna change the latency today and see what it does.

Lol you guys are having issues similar to mine, just totally different setups. I'm running VE injectors and a N60 maf, with the fuel at 4 bar, on a NA motor lol. Needless to say I've been messing with some stuff, and now have the idle and wot good, and crusing afr's in the area they need to be for now. I'm going to wait till I can get someone to ride with me and adjust the fuel map for cruising since I can't do it and drive at the same time lol.

Fwiw, at this point my latency is all the way up to .95, and my k-value is 27k. I've also changed portions of my fuel map due to not having a stock 02 sensor anymore, and the ecu not being able to use the feedback sections of the map.

The only thing that happens with mine is when it's cold, the first few shifts it will fall flat and the afr's will go all over the place, but once I drive it a couple minutes, it will smooth right out. Once it's warm, it act's pretty d*** well, when you shift it shuts the injectors off and all you see on the wideband is ---, and it's smooth as can be. As soon as you hit the gas again, the afr's drop right to where they should be. The only problem I'm having is it runs a little lean when it first starts to spool, but once the boost sets in, it's right in the mid 11's.

I think the problem with the cold running is in the cold throttle enrichment and the cold timing settings. I've been playing with those, and they def. change the way it runs, but haven't been able to find anything better as of yet.

Well I've been messing with this all night. I got the lean stuff to go away. I ran the latency at .70 but the problem is this makes WOT WAYYY rich. I tried turning the K value down and it didn't really do anything. So I played with it some more, got to i believe .73 latency 315 K value and no leaning out. High 10s at WOT though. I have my fuel map at 11.89 from like 3k to 5k and 11.60s from 5k to 7k. And I've got lowwww 11's at high rpm. I'll get it down eventually.

And Silver, that's the same problem I was having. That falling on it's face is not good lol I guess I'll have to deal with some leanness between the shifts.

I still cant figure this out guys, lean during cold shifts and on ocassion it does it when it's warm....


Any ideas?

What exactly do you mean lean on shifts when warm? Mine has always cut the injectors on shifts when warm, so the wideband shows ---, and it's as smooth as can be when warm. I always thought it was supposed to do that. Is your's doing something different?

I know when the throttle is lifted off the car goes lean like ---. That is how it's suppose to work but between shifts it's like 16's. Cold it does like 17s and --- unless i shift really fast then the a.fs stay up.

I guess I don't know if there suppose to shoot lean or not between I know rich makes it backfire but it doesnt shift smooth when it goes lean.

Can you send me your tune silver.

Well that tune didnt work out very good. Idle was in the 10s a.f wise I changed the k and fuel map and still does the same stuff. I gotta be missing something.
