So after a good while, I fixed it. It was one of the vacuum hoses, actually, the one going to the SSV, it was cracked. I also suspected of a faulty precat gasket, and the same, it was all burnt and ripped, I changed that, changed the hoses and now it's all gucci.

Today after almost 6 months (not like I was trying every day or something) I got a somewhat ghost bridgeport tune. It's on my laptop so I don't have it in this PC, but once I connect the laptop to internet, I'll upload it to my drive and post some updates on it. It wasn't hard, it wasn't easy either...

Hey, sorry for answering this late, but yes, I did check everything mentioned, and I had no luck. I'm suspecting of a faulty upstream o2 sensor.

Walle has posted a good write up / discussion you can see in this thread

Wow man, appreciate it. Thank you.

So I've been logging stuff with vt, and I've found out that with whatever map I use (lean or rich or stock) both my Actual and Desirve AFRs are 15.1 to 15.4. I've been messing around with stoich but I turned it back to stock a while ago. Could it be dirty carbonized plugs? Or maybe carbonized o2 sen...

Bump.

The list is getting old

Ok, a little update on this. So I did it....... 15.1 AFR at idle and cruise loads/rpm, I got 7.1 L @2900 RPM/15% load, and 7.9L @3600 RPM/35% load (120 km/h, 65 or 70 mph I'm lazy, I'm not converting it). aaaaanyway, I got what I wanted. It's not enjoyable at all (I have many other tunes for that) b...

No big deal for the 2nd o2 sensor, since I have it disabled since day 0 of having VT. It's kinda safe to go leaner than 14.7 up to 15.5 on race extensions since it won't get that hot (plus, it's in closed loop and up to 0.4 load), but I don't find the way of doing it since the limit on the fuel map ...

Is it possible with VT? I'd like to go 15.2 AFR @low load/low RPM (half of closed loop basically). Do u guys know how to do it with VT, or is not even possible?

Cheers

Can you alter dwell for stock coils or are they already at there optimum/limit?? Better late than never. Stock coils were tested at way higher limits than they are stock, but at the same time, you'll just worn them out quicker. How quicker? Less than most aftermarket (excluding AEM and some others)...
