Tampa 928s

Looking to purchase 1985-86 LH

Kevin in Atlanta

I have a set. They are chipped. Custom chips.

Don't need a chip just need the 928 618 123 04 lh only.

Any one ever replace the injector driver transistors? Any links to parts or electrical diagrams?

I have a couple of extra LH2.2 (and EZ-F) boxes.

Just one transistor for injectors.
I've seen a board where it's been replaced (when L-Jet injectors were used).
The heat sink rivets were drilled out and replaced with small screws and nuts.

The other component on the heat sink is a voltage regulator.

Is it possible that the current draw on stock injectors 24 lbs pulls less current then a set of 42 lbs.
I am interested in the LH can you let me know what you want for it.

Benton

I have an 03 available as well as EZK to match. $185 shipped for LH or $265 for both.

If both types are "high impedance" (about 16-19 ohms) then they would be fine. It's bery unusual for an LH inj. output stage to blow. Check carefully for a short on one of the injector connectors. Maybe there are some bare wires under one of the boots that was shorted when you were installing the new injectors ?

I can repair your LH for you....

I agree, I have had my LH ver 4 with the 28 socket in and out to do an A/B comparison to the loaner 24 pin socket LH. My LH will not run with Murfs Stage 3 chip the Stage-1 runs fine. I will do some additional testing but this seems to be what I am dealing with. With the loaner and stage 3 chip it did not stall but A/F was jumping all over the place. I believe with a little playing with FP it may get better.
So this is why I am looking for a used LH it does not seem like it has a problem just not working with the stage 3 chip.

PorKen

Have you ruled out the MAF and/or O2 sensor?

John Speake

I didn't realise there was a Stage 3 kit for the 85/86 cars..... you don't have a Stage 3 chip for 87> by mistake do you ?

I don't think so it is marked 85-86 and believe it came from Shane's burn.
