TPS Value and LV8 Value

[salvageV6]

Anyone know the approx. TPS value at 25 mph on the rollers?

Will take surface road data as well.

And LV8 approx. values if known as well.

TIA

I'll have to get near a dyno, maybe Monday. What are you trying to figure out? Are you interested in 15 mph also? Maybe TurboJim is near a dyno this weekend

Salvage:
I happen to have some DS runs of a friend and I doing some dyno/chip testing as he works for the GA. clean air force.

MPH=25, TPS=0.66, LV8=64 ,MAF=18.

Sounds very reasonable those numbers.

I am just trying to find a trigger point for my EGR simulator so it can trigger off TPS for emissions use.

Got a chip in the WE4 with no EGR in it, 55lb. inj., and I built a simple PWM controller to output 15% or 20% EGR to more easily pass NOX with it. Almost failed last test.

Other car I found an EGR chip for my Bosch injectors in that car.

Gonna try it with TPS set at .55 volts as a trigger.

Next question is what EGR is commanded at LV8 of 64?

Stock type chip code should work okay.

TIA

I saw right around 40% EGR DC with the above other values.

Great information thanks.

Think I'll shoot for 30% for starters.

What is the timing on the stock chip at that lv8 value?

 

[BoostKillsStres]

In the stock BBKJ image at 25% LV8 the timing values start at 400 and goto 2400 in 200 increments then next is 2800 to 4800 in 400 RPM increments, here are the values starting at 400: 23,24,24,30,30,38,44,42,44,44,48,42,42,44,50,50,50.
