ITS (or anyone) ECU upgrades that will fit in a STOCK ECU housing

IT rules now permit ECU upgrades, as long as they fit in the stock housing. Is the stock ECU "chippable"? Any ideas?

Hmm.. I bet you could fit the internals from a haltech into the stock housing. Do the rules say anything about that?

If the rules read like you wrote it that leaves a lot of room for interpritation. There will be people building very expensive, advanced ECU's to fit in the stock housing before long.

I think there is a chip. I'll see if I can't find more info.

Be careful about the questions you ask. From what I have gathered in my limited research of the subject, most "upgrades" are directed at helping the low RPM deficiencies of the rotary engine in a street/auto-x environment.

Carl has always been straight forward with me, and I have no reason to doubt any claims he may have regarding the ECU mods. I am also sure that he would have real-world testing to back it up.

From my research, I have decided that I will simply have the rev limiter removed (which is cheaper and pretty simple, I am told) and try to build HP from manual manipulation of timing and fuel pressure. It remains to be seen how much "hidden" HP there is in the allowable mods of the ITS ECU rule.

BTW, if anyone wants to PM me for the info on who can do the ECU rev limiter upgrade, feel free to do so.

how much does it cost from SASracing?

I'm guessing they just raise the fuel curves and advance the timing on the low end, then back it off on the high end. Maybe I should call

I did not want to post the contact info for the guy doing the rev-limit mods until I had his permission. So, after speaking with him today, here goes:

Keith Goldin
Goldin Bros. Racing
305-275-0365 - daytime

The mod is $100 plus return freight, and Keith is great to talk to. He owns/drives a 3-rotor 3rd gen GT car that has run many 24 HR of Daytona races, in addition to campaigning an ITS RX7 in SCCA competition. Give him a call - tell him Chris @ Racecar Engineering sent you.

Strange: I talked to Carl about it 3 weeks ago and they gave me a quote. Oh well that 500 can go towards a Haltech.
