I'm BACK! with an S-10, shes ready for some tuning!

I'm using EFI Live for OBDII, which is expensive. I find it very interesting that a very common upgrade for the 96 S-10 PCM is the LS '0411.

Hmmm... so the RoadRunner should work on a Vortec as well? Guess I'll be looking for extra PCM plugs.

I'm not 100% positive, but I'm thinking the biggest reason for upgrading the 96 PCM is because the OBDII data logging / flashing software available for the 96 S-10 is non-existent?

If you are looking "more for gas mileage" CAI is not going to give you a lot more power, but it will hurt MPG.

in my experience they have helped with mileage. Worked on the 96 suburban, the 95 Caprice. Why wouldnt it work on my S10?


So is it better for me to just buy either of these??

Well in theory, all thing remaining the same, colder air going into the engine should require more fuel than hotter air. Now if you have a restriction in the intake say from a lower than adequate flowing air filter then putting a CAI may help by eliminating excessive vacuum, i.e. pumping losses.

Just one of those but can go elsewhere and save $150...

I just did summit because i had the page up and was looking but yea anywhere else. Was also thinking about sending it to Alex at PCMperformance, he did my caprice computer. JW is all. Kind of bummed i bough TP RT and cant use it now :(

Well if they are replacing the Vortec PCM with LS1 PCM the RoadRunner should work. RoadRunner is an LS1 replacement PCM for Real Time tuning LS1. Probably more to it then just changing PCM plugs though. This will be a step into future tuning for us.

Here is an example of what I'm talking about:

http://forum.efilive.com/showthread....98-Chevy-Truck

"My project was a 97 V6 C1500. The four current PCM connectors need to be disassembled and the wires installed in the new 80 pin type connectors. You will need full schematics for each vehicle and plenty of patience. Work out all details before you pull out the first wire, many are the same color and very difficult to identify afterwards. This gives you the later model PCM benefits and RoadRunner capabilities."

I've never had much luck freeing up mileage in the 4.3 S10 family. I tried switching one vehicle to 4.10 gears and removing the loose converter and that seemed to make the largest difference. That 2000 - 2500 rpm converter plus 3500#+ weight really takes a toll. We currently have a '95 which has the strongest version of the 4.3 other than the turbo engines and it's actually not too bad for power. Mileage is still in the 16 range without fuel additives. I think the strongest combination of factory parts would mate the 95 cam and dual runner intake with the 96+ Vortec heads but it's not a simple bolt on process and you'll need a circuit to switch the tuning valve at the correct rpm. In terms of power you'll find greater gains by working with the exhaust side than the intake. No sense letting more air in if you can't get the exhaust out.

Several years ago I built a 302 Chevy V8 with an LT4 roller cam and 6" rods to put in the '95. I still haven't done it but I think that swap is likely to net the power and mileage I want. I'm fully expecting that a '96 style black box controller will do the trick for this mild engine. The largest shortcoming of the black box is a mysterious rev limit which may be due to the hardware at (IIRC) about 6200 rpm. The Pacific Performance forum was a good source of OBDII truck info a few years ago.

I'm in 100% agreement with the above comment! I'm curious where to get software / hardware to reprogram / flash the 1996 black box type computer? It's my understanding that 1998 and up black box type computers are supported by aftermarket software / hardware but 1996~97 are not?
