Going to try to get an hour in programming the ECU in the morning of the 31st.

Hopefully I can stop the car from spewing so much unburned fuel and get it to idle properly.

I need to set the K values to start, then work on the cold start enrichment so I have a car to drive this winter if I'm desperate for transportation.

Also still need to pic up a radiator, as well as some silicone couplers for a special project... if I can find funding.

A "special project"??? :shock: The whole job sounded special to me, from Day One.

Should we worry about this? :twisted:

It's cold, that's what happened.

I can't use the Nistune until I install resistors into my fuel injector harness.

Hi Impedance ECU >>> Lo Impedance Injectors = Bad

I'll get to it tomorrow Noon when it's warmest.

Also my RPMs climb immediately upon ignition, without any throttle input, causing me to kill the engine before it revs past 6000, so I have to figure out what thats about.

tps....timing....

Something along those lines.

Just redid the timing, thats how I got it to start.

I'm using a 60 mm Stanza TB and corresponding TPS so I'll double check that is what's needed.

I believe I'm suppose to use the specific TPS for the TB, but I have another Z31 TPS just in case.

Also need to check my Idle controls, etc.

*Remember to wear two pair of socks working outside this winter.*



Installed dropping resistors, got my ECU to talk to the PC and adjusted the injector size.

Car started up with minor hesitation revved then died.

Need a new CHTS sub harness and find some more vacuum leaks, but that's pretty much it.

Just need to get it warmed up and move it into the garage for storage.


Just because you guys like pics
