Unfortunately, I don't know of any program that will do this. Innovate Motorsports has OBD2 datalogger that connects to the CAN port and logs with LogWorks, but I don't think it'll make tables for you. Of course, you can always go with this and write a MATLAB script or Excel VB script to compile a table.

One word of caution though - you really need to do all measurement with a constant water and intake air temperature. Otherwise, each data point will have a different fuel/ignition trim applied to it. This will be difficult for most people. You also need to do all your testing with the highest octane gas as you can find to make sure the ECU is running as close to MBT as possible. For the same reason, it's better to do the testing with a cooler running engine on a cold day. It's also better to do this with an engine that doesn't burn oil and doesn't have excessively valve lash.

 

I actually thought about that a lot, bring the motor to operating temps, and deduct the necessary values according to coolant and intake temp, there is a formula for each I just need to find them again on Google, or work with what hondata shows for temp adjustments

 

Unfortunately, there is no formula that applies to all engines.

 

There is a formula for intake temps vs enrichment, as far as engine temp vs ignition /fuel I think it wont be that bad, having a raw p2p timing map would be nice but still having just the output timing can be sufficient enough to plug in a obd1 ecu and make small adjustments in open loop till it feels good then let closed loop do its thing, either way should run 20% better at least vs running stock z6 maps on a y8, its mainly the ramp I'm curious about and when it levels off at, and what is the Max timing at 0"

 

Are you thinking of the Ideal Gas Law? That can sorta work for IAT compensation.

ECT compensation depends on the surface/volume ratio of the cylinder, sleeve/chamber/piston material, cylinder turbulence, type of coolant and its speed, etc.

 

So then we agree that the z6 map is not the correct way to run a y8, yes and no, if what you say is true then no one is warming up their obd1 controlled y8s correctly , but on the same note, carbs only had a choke LOL so without getting to crazy with technicalities, I'm just looking to plot a y8 timing output map from a p2p ecu in action, by knowing exactly what the timing at the crank is in light to heavy loads we can better help y8 members have a drivable n/a base map, just like the z6 and po8 maps givin in most tuning programs, its just plain retarded in my opinion that there is not one to be found online, yet hundreds of obd1 engine maps all over.

 

Oh yeah, I agree with you there. Whatever data you take will be fine for a basemap as long as you don't run crazy different operating conditions. I wasn't sure how accurate you wanted to be.

 

Just more accurate than z6 timing, being that it has a different combustion chamber, and slightly different angled cam the map should theoretically be different all around
