I guess I don't see what kind of data there is to collect without an IC since there is nothing you can change to impact it. I guess my concern is that if they're already limiting timing at 250 F with a 3.5" pulley, what are they going to do when they see 300 F (just making a number up) on a 3.0"? I'd just hate for them to go crazy pulling timing because of that.

As far as the cam, I wouldnt bother checking it at this point. It's already in, so it's too late to do anything about it. It's not like it's going to change the tuning process if it's one vs the other.

 

 

 

You install a wideband, you want about 11.8 on a wideband. You add fuel or take away fuel until you have that.

You monitor knock, add timing until you get knock, then back off. Then check your wideband some more. Then you adjust until you have the best timing table, without knock, and not running rich or lean.

Tons of information online, lots of tutorials floating around. The PCM on these 3800s are very basic. They are a pretty good one to learn on, as they don't have too many random multipliers and table modifiers outside of what you are looking for.

 

It depends what your goal is. If your tuner tunes the car, and you're just monitoring it, there isn't much to look at - KR would be all I'd be concerned about unless you had a wide band piped in. I wouldn't screw with the tune once a professional has dialed it in, especially just getting into tuning.

If you're intending to tune your car yourself, Chibi gave a good 30k foot level overview. There is a lot to it though, especially to a good tune. I'd suggest getting on the hpt forums and just reading away in the v6 section.

 

 

Sorry to hear, time for some junkyard shopping!

I'd definitely try to figure out root cause on the old engine though. It's not common for them to eat bearings like that and you'd hate to have a repeat issue.

On a side note, there was an interesting thread on a Facebook 3800 page the other day. A few people claimed to be running a 2.8" pulley with similar mods to you, and others even a 2.7" with slightly more mods. So hopefully you can really start making some power once you get it back on the road again.

 

 

Ouch, I bet you're right - They definitely should've honed the mains. To be honest, it doesn't need main studs anyways though, I'd just do a junkyard bottom end next time around, especially if you're sticking with the m90.
