It'* running smoother, because it is...I found 2 crossed ignition wires Not to mention fixing the TPS (I think...I will need to verify it through a scantool). BUT...now I am leaking fuel on the front of the fuel rail somewhere. I've got another fuel rail that I am fixing up, and I would like to try out S2 injectors while I am at it.

That would explain the misfire.

You know I happen to have a set of perfectly good stock S2 L67 injectors sitting at my house.

...and you won't for long

I have another set of injectors I can throw on....actually, I think it'* just an o-ring that failed, so I should be able to fix that right up.

Tuner is in the mail today...I should get it Thursday or Friday OH YEAH....one more thing...the guy gave me access to the account it is associated with. It doesn't have the four credits like he promised it would have......









It has eight

That vid was cool
The car sounded great, with the tuner you'll be able to have it purring like a kitten.
Congrats on the conversion

You got one hell of a deal on that tuner if there'* 8 credits on that account. Once you get the car drivable and familiarize yourself with the tuner you'll get to enjoy the seemingly endless task of finding the perfect tune...especially here in FL where the weather seems to change every few hours.

Now that I got the tuner, both Aaron and myself have been going back and forth, trying to find a good starting point.


Now for the not-so-good news. I got a HP Tuner, which goes down to 1997 PCMs. Keep that in mind. Now then, I went with a 97 PCM because I knew the PCMs were the same between the L36 and the L67 (difference being the L36 uses the 60E and the L67 uses the 65E), so I figure the options like boost control could be turned on in the L36 tune.

WRONG. At least I think so.

Turns out even though the PCMs are the same, the OS for each is different. Meaning I can't put in boost control for an L36, nor can I put in 4t60 tables in the L67, or at least, that'* my impression. So, the one file I can use is the 1996 L67...which HP Tuners do not support

Right now I have a modded L36 file in the PCM, just so I can move the car out of the garage and get some gas for it.I drove it around the neighborhood last night, and aside from getting NO boost, despite me running a 2.2 pulley, it drove ok. I may very well have boost, but the MAF tables are so out of whack the PCM may not even command it.
Any thoughts on this?

EDIT - I guess putting out the mod list would help somewhat, just to get an idea of what'* going on. 2.2 pulley, S2 L67 injectors, P&P Gen 2 with matched TB, stock 93 L67 MAF sensor, ported lower.

Those S2 injectors will cause you more trouble than you'll be able to tune out. They'll be running at a very low duty cycle.

You'll have much better luck bumping your fuel pressure up to 3.5 or 4.0 bar and tuning with the stock injectors. Especially since your engine doesn't use fuel at the same rate (lower rpm'*, not as quick to rev) as the S2 L67.

In a sense, your injectors (36lb) are trying to 'drool' the fuel into the cylinders.

Couldn't I set the duty cycle of the S2s a little higher in the interim? My dilema (sp?) with my stockers is that I removed the pintle caps after I found several of them damaged, so I need to send them out for refurb. Plus I found one that did leak, and stupid me didn't mark it.

What differences are there in the 60 or 65 as far as control goes? Wouldnt you better running the right engine program and playing with the trans tune?
