202 UC Torana/Delco Conversion

I fitted another TPS, this one has some effect but still triggers "low TPS voltage" error. I'll see if I can get another, can't get a new one for a few days.
Here's a log with the replacement TPS. What voltage should be showing for the TPS volts?

Start up 7.xdl

tps should be 0.45 v throttle closed or it can spit errors

[Jayme]

your tps volts are fine in that log, the error code might just be in memory from last time. try removing power from ecu for a bit to clear the code.
did it fix your lean spike issue?

Thanks delcowizzid & Jayme.
Jayme, If you look at the log at 2.47, 4.10 there is still a slight hesitation, but I may be able to tune it out. I'll disconnect the battery in the morning.

The TPS fixed the hesitation problem. I've now driven the car on the road & done some tuning. After some initial problems with "pinging" from 2400rpms, which I also had when the engine was fitted with a carburetor. I've now got a tune that is acceptable to drive.
The following tune is how the car was driven with the following log.

V111$12P-V1.2.12-202.bin

Road Test 4.xdl

I have altered the above tune(which is still pretty crude), but haven't tested it as yet, my wife called me in for a baked dinner, but I solved the "pinging" problem.
If you look at the beginning of the above log, the engine takes along time to start(maybe fuel related), & when cold it's even longer, I'm not sure why, but with a carb fitted started very easy.
Can some one check this out & see what I may be able to do to fix it up.
Thanks in advance.

try increasing the crank fuel pulse width tables, increase them by maybe 5% and see if it makes a difference.

[v6bucket]

Thanks Holden202, "Map A:crank-first stage crank base pulse width vs Coolant temp" &"Map A:crank-second stage crank base pulse width vs Coolant temp" are these the correct tables? If so, I can adjust them by 5%, then save, when the table is opened again only -28° up to 32° has changed & 44° to 116° revert to the original figure. What am I doing wrong?

[Holden202T]

well it looks like 124.51 is the maximum for the table, but when i multiply the table by 5% it seems to update properly for me.

maybe a corrupt file if yours isn't ?

and yes they are two the tables you need to change assuming you are running on the map a tune.

[v6bucket]

Thanks mate. I had a play around with the tables, & found that I can multiply the table by 11% & over but not less than that. The number in the table reverts back to the original. I haven't tried the tune in the car yet, I had to finish porting a set of heads for my mates blown V6 Dato & ordered a set of 60lb injectors for it.

[Holden202T]

thats a bit strange, what numbers are in your table ?
