ECMlink WOT lean

[Jt_4g63]

Please look at this log I dont' know whats going on. WOT car goes lean (16-18). At about half throttle with car in boost AFR ok (13.0.1) "could go richer" NEED HELP
I think its MAF comp but not sure.

I looked at your mods and it says your MAF is hacked. Did you remove both honeycombs, or just the unmetered one? If you cut too much or removed both honeycombs, it can cause a number of problems, including rough idle, dying at idle, rich or lean conditions.

 

[Jt_4g63]

yes its hacked but just one honeycomb is out, the unmetered one

I'd say put a 2g MAF on. In the first pull, it kinda looks like it was getting over run. Also you've made sure your base timing is correct right?

What does BaseTipInTpsAdj and InjbatteryAdj do?

This is a pull i did today, I played with mafcomp.

Should I play with fuel adjustment table?

 

[MY1GDSM]

what does BaseTipInTpsAdj and InjbatteryAdj do?

BaseTipInTpsAdj

Basically Adjusts the IPW based on the TPS Change,If you increases it it increases the amount of fuel injected on throttle tip in

InjbatteryAdj

It adjusts the IPW according to the battery voltage, and is added to the final pulse-width

or play with mafcomp more

You should figure out why your leaning out under boost ...
Is your Fuel pressure raising 1:1?
Is your fuel pump rewired?
When was the last time you changed your fuel filter?
Also
If your doing pulls in boost you should set your open-loop thresholds back lower... .

i think my Alternator giving problems going to rebuild it tomorrow
here r the logs

IMHO Unless you address other issues that have nothing to do with V3Link you gonna continue to have problems or hurt your motor... .

Your not getting the fuel like you should your going lean (as soon as you get into boost) Like I asked before is fuel pressure raising 1:1? or maybe it's your w/b is not reading right... IDK I can't see your car... .

But either way, you can Keep raising you Maf comp table and it's not gonna fix it... .

I don't mean to be rude but are you looking at your logs? Notice something wrong with the highlighted areas?

 

[Jt_4g63]

yes the fpr is 1:1
i am about to order a 255 walbro and a fpr

 

[MY1GDSM]

yes the fpr is 1:1
i am about to order a 255 walbro and a fpr

But you do you have way right now to verify it's actually raising 1:1?

So Wait, You don't already have a 255?
You have in your profile you do...
