Block 115 questions?

Can anyone tell me what the values in Block 115 represent? I am also quite interested in what factors create the Load%(whatever that is). It appears that the higher the load, the higher the boost. I have compared two chips under consistant conditions, yielding quite different results. One drops boost over 5K quickly and the other does not.

Thanks in advance,

Use 204 & 120

rpm,manifold press, cmd press, turbo press

rpm, torque limit, net torque, ASR status

Re: Use 204 & 120

Should I log these simultaneously? Any idea on the Load% meaning?

Yes & it has to do with the fuel load, I have a note of it somewhere.

Percent of stroke or some such thing I'll look for it.

Could that cause the ECU to reduce boost as well? I need a few more pieces of informtion to be able to diagnose what my car is doing.

Any help is appreciated.

Check blocks 20 & 112

20 has the timing corrections, the more retard the greater the exhaust temp, 112 has the exhaust temp reading for control. Range is 950 to 1030°C, if under-range temp pegged at 950°C. When it first gets on line it usually dips under 950. Fuel is added to hold exhaust at 980 if temp goes over. You can get more power reducing boost & increasing ignition timing and A/F ratio if things go to far. Block 120 will tell you. High boost & high flow also gives high inlet temps. Block 221 has throttle opening, ignition timing, coolant temp & intake temp, check this also. Only compare when 100% throttle opening.
