There is a torque reduction spark table, its the minumum spark the engine will pull during torque reduction, that is the table you are looking for....

Any history on the car? Does the valve train make any noise? Also yes what he said^^^^ Compression Test? Logs are useless and too short or crash...

GM Gen4 Injectors v2.1.xls (this is one of those times when I am really mourning the loss of the tag)

Yeah, I realize timing = torque in this case. What I was looking for was the mapping which translates between the two. I see the TCM tables direct...

2 of those data logs make my scanner app close. Makes it crash. What's been done to the vehicle? What are the mods? Sounds like it's time to...

It's not the rear main seal's fault. It's the hurt piston. Time for a leak down test. A catch can isn't going to fix it. Big valve cover vents aren't...

^^^ None of that matters until the VE is straightened out.

As I said before, 100% it's a miss on bank 1. Whether it's injectors, coils, plugs, wires or mechanical, it's a misfire on that bank.

As a result of some mails from and the support I'm sure there is no further development of RaceRender. And this problem is at least 3 years old...

I'm looking for the injector data for the 12594512 injectors. I'm using the ACDelco 217-3299 Fuel Injection Pressure Regulator

I did try with Simos tools first but couldn't get pass the stock torque limit, it looked like the xdf was missing tables for the dsg. can I send the...

The GM data is for a 4bar/58psi fuel pressure setup. The discontinuities of trends in the low rpm/low map regions of the VE table show this. In...

timing IS torque Decrease the torque reduction and it will pull less timing Log it n see I doubt that’s all it is tho…

will do just got my interface in yesterday.

Thank you Roller75 Just got my interface in yesterday Gonna try to get on this next week Phillip

I am using the data that I was given from the injector provider. They sent it over in a file. I can compare and make sure I copied appropriately....

What I got my new computer I emailed the parameter access file to myself

And since we're being contentious 799 heads are not the same as 243.

Since you've set FPR to 3 bar has offset and SPA been adjusted? I'm seeing some problems with VE at low pulsewidths, and this is a good indicator of...

Yes bias toward IAT, which is zero. No recommendations on PID's. Keep an eye on them and adjust accordingly. A few of us were on a thread a bit...

I have cammed probably 20 of them now and yes some did have 243s on them. I was in doubt when I saw them before until I cammed my buddies 2002. He...

Ok, I was manually controlling the NBo2 sensors. I will set my NBo2 voltages to 450 and see what that does when I go back to NBCL tuning. I will...

It's because you're tuning VE with a wideband. STIT goes high when the narrowbands come online. There are heater circuit codes for both, so they...

Still very limited. Log what you need.

I did , would this be a cookie on my computer or just me login in HP tuner would work ? I might have done it on my laptop . This moment I am on...

Yes get the cam position sensor problem fixed.

Have you tried taking the HP Tuners emissions training class to gain access to emission settings?

-Try going Engine ; Fuel ; Oxygen Sensor the disable heater . But it will probably will turn off Sensor 1 heater as well I found that in an older...

These engines seem to have ring issues from what im seeing with higher mileage. They don't seem to be as good as the l83s or l86s in that regard....

update. polling didn't help, so I put it back to default 200ms. replaced plugs and wires, didn't help. replaced o2 sensor, only on that side...
