Getting my car up and running now and got it to start pretty well off the bat and with a bit of tweaking it idles some but not for too long. Wondering what kind of k-value I should be using and such. Also when it first starts it starts really strong and then after it goes for a bit it gets really rough and the exhaust smells like straight gas. Seems like maybe once it gets into the tables it's bad? But also looking at the log for some reason the target a/f ratio went to ~6 (explains the gassy smell) and I can't figure out where its getting that. Having a good set of base values would greatly help.
Important mods to note: Id1000 injectors, wideband maf, it's a tt, bigger fuel pump I forget the exact size (320?)
Any help would be appreciated to help speed the project

K value should be [current K-value * (oem injector size in cc/new injector size in cc)]

for it to hot start correctly you will need to mess with the crank enrichment table.

No idea what you mean by wideband MAF.. and fuel pump doesnt matter. base fuel pressure does...

Also since it seems you have no idea what you're doing I would pay a reputable tuner to tune it before you blow it up.

Using a different maf (couldn't remember what it's called) requires a different sent of values which is why I listed it. And I do know what I am doing but it is hard to isolate a problem when you have tons of variables which is why I asked for people with similar setups to suggest their base k-values because the finer tuning of all the tables is much harder if that's not at least close. I've been doing what you said but adding back in some to account for the maf.

For a different MAF unit you should be tuning it in by adjusting the MAF table, not K value. You should compensate with K value if the MAF tube size is different. Uprev also has preset values for their uprev MAF and HPX maf which will get it in the ballpark.

Got pretty close on the k-value, just started to lean out once it came off of the cranking enrichment. It's at ~17,000 and it actually hit stoich when the target a/f ratio was about 12. Once I get that down I'll be in the ball park for at least the lower part of the map. Then some tuning for some sick nasty boost

I like how you guys are hating when it's working

Is it though?

Not hating, just not confident in you self tuning WOT and expecting something to break.

I did help you get a start on the tuning after all.... But suggested a full tune from a reputable tuner after its running.

Save yourself the stress and do what the man says!.There's nothing wrong with knowing how your system works/the basics. However, having a PRO tune your car will be cheaper and less stressful in the end!
I promise
