Unichip stock map to avoid CELs

[pwells]

Hi,

I have a unichip on my BRZ, but it's giving me a few problems with CELs at idle (ie. after long trips, stuck in traffic etc.). I'm assuming this is because it's tuned for American cars and weather etc (I assume this is to be expected, but if not let me know - code is maf voltage low).

As I don't really need the car to be more powerful for daily driving I was wondering if there was a stock map that I could run every day which does not affect the ECU at all, and the switch to the performance maps for track days.

Does anybody know if this is possible, if so where would I find such a map? (I looked in the unichiptuner database, but could not find one). If not, which map would be closest to stock?

Thanks.

If you are getting CELs and want to go to a stock map that doesn't affect the ECU, I would just un-install. I wouldn't expect unichip to have a stock map since it doesn't flash the ECU only changes signals to and from it. I wouldn't think tuning for weather variation would be a factor since weather extremes in America are similar if not greater than in Aus. It wouldn't be a bad idea to make sure the CELs aren't a more serious problem with your MAF sensor.

Did you get in touch with the Unichip folks? They seem to be very helpful.

There is a stock map in the DB but it's not the straight "pass through" the way you want it, just a map optimized for cars with no bolted-on parts (probably as close as you'll get, though).

I've unplugged it for now, but it would be simpler if I could just flick a switch when I'm at the track - saves me fiddling with a hot engine and burning myself, but if that's the only option...

I'll keep an eye on the MAF now that it's reverted to stock, but the CELs only occur in ~40+°C (~105+°F) days when idling for extended periods (ie. stuck in traffic) so I figured it was just the heat.

Also I should mention, I have the Perrin CAI and inlet and am running the '92 Perrin CAI + Timing ~ Fuel ~' map, using 98RON fuel (about the same as 92 octane).
