Timing tuning, How to?
What is the best way to get my timing set correct on my large street ported rebuild. plus I think my TPS is out of whack. Is the TPS diagnostic 3 prong green female harness near all the emissions harnesses? cause I cant seem to find mine and that is the only 3 prong female harness in my engine bay?

I think he means the actual diagnostic plug which is located on the drivers side of the engine harness.
If you have a T2 stock harness then yes it is with the different colored emmisions plugs(green 3 pin female connector)are you using a TPS adjustment tool?
As far as your timing I would go by the book , advanced 5 degrees leading and 20 degrees trailing unless you're on the bottle (NOS) in which case you'll want to retard your timing accordingly.You should be able to use the timing marks on your lower pulley.

If you're running the stock ECU, RUN STOCK IGNITION TIMING SPECS.
There's no reason to be messing with the stock ignition timing, and go either way can cause damage to the motor if you don't know what you're doing.
There's a little known fact that the rotary engine does not respond as well to advancing the ignition (versus piston motors), so is it worth taking the risk?
No.

So how about if you have an aftermarket ECU?
I would really like to hear your reccomendations.

I don't give out recommendations to "shoot for a number", cause every engine is different.
I don't want to be responsible for blowing motors up cause I told you it was oay to run X amount of ignition timing advance.
