I have read the posts on solving the hot start issue with the EMU. Wondering whether anyone is still using one of the suggestions (I.E. Change the injector scaling:130 cc to 260 cc) or other ways to address. Also what had to be changed to make the fix not address other issues.

My car is an 00 with a MP62 running 12 lbs of boost. Running FIC 365's.

Idle is good, never starts hot.

Thanks !

Since there are some views on this post I wanted to provide an update. I scaled the EMU from 270 to 300. It seems to Hot Start much better. It seems to run rich on tip in for closed loop. But it recovers relatively quick to the 13 - 14 range. I tried removing a lot of fuel in the idle area and it seemed to have trouble reaching a stable idle. Currently I am removing about 15 - 25 in the non boosted areas.

Planning to focus on the boosted cells in the next couple of days.

Took the car to the track on Sunday and worked the tune. Have the AFR's relatively stable. The hot start issue is gone. The issue I see is it goes rich in some conditions when you get into the throttle. The ECU leans it out after a couple of secs.

Going to stick with this solution for a couple of months and see how consistent the tune will be.
