I'm curious to see what the lowest TPS value other people are logging is. On my car the (with 0008 rom) the lowest TPS value I have seen with the car running is 13.73. I should probably also try logging it with the engine off.

Is anyone logging TPS values 0 or something lower than my car?

It all leads into another issue I am seeing where over half of my driving, even fairly gentle acceleration & freeway cruising, show my car's load value riding firmly in the "260" column. I have improved the VE considerably, but want to make sure I don't also need to recalibrate my TPS before I start tuning.

From what I've read, I will probably need to rescale the MAF table and the load axis for the timing & fuel tables. I'll probably try to avoid making boost adjustments until I have a 3 bar MAP sensor and can rework my rom for that.

 

tps idles at 13.7 +,- that is correct.

260 load is not right for cruise, but some one else will have to help you there.

 

Your TPS reading is fine, but your load is WAY off. Depending on your setup, you should be seeing 260 load around 18-22 psi. Either you aren't logging correctly or you have some other major tuning issues.

Thanks for the quick responses!

The load based problem revolves around issues - the car is fairly heavily modified. I'm rescaling the load based maps now to see where things land. With the current mods the engine should be moving a fair bit of air.

 

with the car of i see a TPS of 12%, max is 99%

 

More info about my odd load values .. it turns out that my load values are just fine when I pull them up in a spreadsheet. I had been experimenting with MapTracer and that is where things seem to be out of whack.

In MapTracer when I replay a log, it spends about 50% of the time in the far left column. The actual values from my the log show maximum loads of about 230. That makes sense since I've sported the car a bit, but haven't floored it yet. I'm on the later stages of (rebuild) engine break-in and not quite ready to go all out.
