Timing Maps W/ Alky or Race Gas---Screen Shots
Post up your screen shots here of your timing maps with Either Alky, Meth, Water Injection and Race Gas and please specify which one you are running
Here is my 93 pump gas with 100% methanol timing screen shot.. you tell me- to conservative??

could you tune the high fuel and timing maps for alky or meth..... but keep the low fuel and timing maps tuned for fuel only..... like a safe map if you run out of alky or meth so u dont blow the motor........ would the ECU react fast enough to switch maps?

ScreenHunter is a nice free screen grabber program saves time over using the digital camera

Comments/questions:
- It's really difficult to know whether this would represent a conservative or aggressive tune, since we do not know the modifications of your car, nor ambient conditions. Even if we knew all that, there would still be car-to-car variance to account for.
- Why would you run a huge, flat plateau of timing in the 180-260 load columns?
- Why reduce the -10 degree timing area in the low rpm/high load area of the map? It's my understanding that it is there as a safety net, since you really should not reach that area of the map on a stockish 4g63.

It is really not possible to judge your tune without datalogs. Knock counts, logged ignition timing numbers, meth pressure, nozzle size and spray volume are all needed also.

Although I have seen straight pump gas maps that are more aggressive in the midrange.
