yes I have the good tune saved in my image file bin

I going to install new a rev 15 board, I dont think I need to set the resize injectors If I just set my Injection muliplier to 376 (old resize value) right?

I was going to have a full tune on my car, The tuner does not think my knock sensor is working. He does not like how it can not be displayed while tuning. my other problem is that the 02 sensor shows it not working, Im goint to install a wide band this week. So How can I tell if the knock sensor is ...

I found my fuel temp reading wrong, it should ambient when its cold. it reads apx 260deg cold. I checked the ECU wire connection good. My fuel temp reads apx 80 deg after the car is fully warmed up. So then I get a hot restart because my fuel pressure regulator contol valve will not increase fuel pr...

I may have figured it out, I may have had my fuel tank vent line blocked off, when I removed the charcoal canister.

Yes cold coolant and fuel temp good when cold. I just cant find the warm/hot restart adjustment.

my car has hard times starting after its fully warm, If it sits for 10-20 min. Im not sure what to try, When it does fire up the it runs on one or two cylinders and slowly starts adding more cylinders after apx 20 seconds I have all 6 running again. I do not see any hot restart adjustments. Most all...

I was under the understanding that 1984 to 1987 ECU's had 2 injector drivers, These models had a recall, the factory rewired the injector harness so the engine ran on only two injecter drivers I thought 88-89 ecu,s have 6 drivers, So if you used a 88-89 ecu on a pre-1987 you had to rewire the inject...

Just wanting to verify the correct way to set base timing. if the timing light shows 15 deg at idle then my lap top should show the same ?

here it is

here is my data logs line 131roughly is where i get the shutdown

we set the k constant at 350 latency at 75 the latency didnt make much difference. the injectors are 420cc

my car sounds like 1SIKZ31 car, from start to finish. when I installed my nistune unit and resized my injectors, My car ran bad, almost to the point it would rev like 1,200 rpm max, thick black smoke out of the exhust pipe, I have it running fair now, not the best under boost, some times it goes pop...

It it possible the incorrect voltage reading can cause other problems ?

I have noticed I show low battery voltage, I show around 4.5 volts. I have a 86 z31 with a 87 z31 ecu.
what should I check to make the battery voltage correct.
