New to forum with fresh tbi install.

Nice work!

Don't think I've even seen a TBI on backwards?

Couple comments... try to move spark plug wires away from EFI wires, can cause feedback issues. Where is your MAP sensor hooked up? SUpposed to be on the rear (front) of TBI between fuel lines.

Your data is showing going leaner as RPM increase. Check fuel pressure!

TunerPro is like WInALDL on Steroids, and it will do the bin editing too...

Lol, S10 with camaro engine and fiero valve covers.

Looks like fun,i'm building a 3.1 turbo hybrid now.
Still haven't decided if i'll try OBDII or $8f though.

The nice thing about the camaro 3.4l is that the block is nothing more than a bored and stroked 2.8L block, so everything attached to the block matches except for no provision for a mechanical fuel pump.

The map sensor is connected to that port between the fuel pipes.

I'm going to check out the fuel pressure and probably increase it a little to see what happens.

The other thing I am curious about is wondering what the timing is supposed to be doing, I have a timing analyzer that I had hooked up at if I recall correctly, it was running about 40 degrees at 2k rpm at cruise.

On the mounting of the throttle body, on the s-10 factory manifold, it actually sits where the throttle cable bracket is pointing more towards 10 o'clock.

I'm going to do the pressure regulator mod on the extra throttle body that I have and see what affects upping the pressure a little will do. hopefully correct the lean issue.

Nice. Cant wait to see this progress. Welcome to the site BTW

[damanx]

Thanks for the welcome.

Just got a new higher pressure fuel pump installed. The old one was only running about 7 psi max. The new one, 115 bucks later is running about 13.5 psi.

Will have to readjust idle and the start from scratch on the numbers again.

Your building up a 3.1L too? What codes are you looking at? Thats pretty cool though man, not many ppl put much work and effort into those engines. Props.

Have you though of using tunerpro for datalogging on the 2.8L? Its a step up on winaldl IMO.

Was about to respond to you eddi about not building a 3.1, but then read back and realized you were responding to playtoy.
