I would guess AFM coz the Microtech runs open loop.

A link to a thread was put on here or SDU a week or so ago that has good info on octane boosting. It is a very long thread so here is a summary: 1) A number of octane booster bottles were tested (using a tester used by NASCAR and others) and it was found none of increased octane by more than 0.6. Some bottles say "increases octane by up to six points", meaning 96 goes to 96.6 not 102. 2) It is suggested that these booster bottles do increase power possibly using long change molecules that deaden and/or change the frequency of the ping picked up by your knock detector. ie. your knock detector doesn't pick up the ping and doesn't retard therefore more power. :eek: 3) High octane fuels have a limitted tank life (as low as 40 days, in the servo tank and/or yours) due to venting of the good stuff. You should buy your HO fuel from a well used servo, rather than a backwater that take months to sell 20000L of 98 octane. 4) 10:1 is the recommend tolulene mix Also I think it's the heat not the lead that kills O2 sensors.

Check the connections of the turbo timer. Might have been badly wired in.

Yep sound like a loose wire or dodgy sensor. Try ECU diagnostics

I read an article from APS that compared ECU's on a WRX that showed some thirst issues. If I wanted economy I would have kept my Civic VTiR

Thanks Freebaggin. I guess this is why many report increased fuel usage with Microtechs. I guess you could tune for economy, but who the hell would do such a thing. It sounds like a good unit, so now I just have to find a local supplier and/or tuner.

A few people said the Microtech runs 'open loop'. Does this mean it doesn't use the O2 sensor for air/fuel adjustment?

I would not rely on IC spray to hold off detonation. The spray on your IC cools mainly through evaporation, rather than the temp of the fluid (tests I have seen show stuffing your water bottle with ice blocks has little effect on the ability to cool in both IC sprays and injection sprays). If you are relying on a IC spray to cool that little bit extra to stop detonation on a hot day you should look fitting a temp warning so that if the spray is ineffective do to empty bottle or high humidity you can drop your boost and protect your engine. If you live in Nth Qld I wouldn't even bother fitting one (for the same reason my Evap Air Con is just big fan in 80-100% humidity).

I recommend a bit of shareware called NetCaptor. It runs as a front end for Internet Explorer and has the following work browsing features: 1) You can view multiple page in the once instance of IE and the pages appear as tabs with the IE window rather than on the task bar. 2) You can minimize it to the system tray rather than to the task bar. With the two combined you can have twenty threads open(ing) and when you hear footsteps you minimize IE and there is no sign that you are browsing except a dot in your system tray. When the coast is clear you just double click on the dot and your twenty pages are back. It's beauty, get into it.
