I hope this is the right section of the forum to be asking this. I normally only tune evo's but i have an evo customer who wants me to tune his friends s2000 with a turbo and e85. Basically I was seeing if anyone would be kind enough to let me know what a good start point would be on e85 for these engines. about what degree of timing should i start at for a basemap on e85 at full boost and pk tq? and around what degree at redline? right now i have it set to 6* downlow and about 14* uptop.. I dont want to experiment because running to retard of timing can actually cause high EGT.

Also I understand boost will correlate to what timing the car will run ultimately, but just want a safe estimate where to start when tuning one of these cars with a gt30R~ equiv turbo with high boost.

Car is being tuned on AEM.
