HAI completely removed as weather warming up. Engine feels more responsive - suspect ECU was compensating for increased IAT by pulling timing, thus negating any FE gains from this mod. Reflashing the ECU might have helped.

running hot air intake, warms up faster, iat about 50-60 degrees about ambient.

doesn't seem to have made any difference whatsoever. maybe ecu is changing ignition settings for the worse.

After 136km on this tank, put 4.55l RE85, so ran most of this tank on about 13% ethanol.

So far running ok, no engine check light on, smooth tickover. Will ideally fit my wideband O2 sensor to monitor lambda at high load, when ECU may be operating in open loop. Will be interesting to see how cost/km is affected by the ethanol fuel.
