Anthony_piselli Posted July 19 Report Share Posted July 19 Testing different ecus on my engine stand, all using the link A loom. one ECU being a v44 and ran into the problem of not being able to calibrate my map sensor. Using a ej20x which on the g4+ software is selecting Subaru V10 under the map sensor options then doing the map sensor calabration command, easy no prob. But on the v44 there's no V10 option under map sensors. Updated to latest software, tried the v9 sensor option but I get the error <5kpa or >5kpa compared to bap when I try to calibrate. Which makes sense. Bap is 104.4 kpa and the v9 with the engine off is 114 kpa and 11 map. Even tried to use the internal map on an volt 5 (not sure if that's the right way to do that) still over 5kpa compared to bap. My workaround to fire the engine up was to run the v9 map sensor option and to crank the fuel main up to 23ms. I believe the correct way is to use a cal table but curious if there's a way to get the V10 map sensor as an option? Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 20 Report Share Posted July 20 I dont remember any of our ECU's having a Subaru V10 MAP sensor option? Our V10 base maps are using the common V7/8 cal. Can you show me where you are seeing this V10 option? Quote Link to comment Share on other sites More sharing options...
D19SUB Posted July 23 Report Share Posted July 23 I have it on mine and asked a similar question I have the 2010 sti hatch type uk Quote Link to comment Share on other sites More sharing options...
Adamw Posted July 23 Report Share Posted July 23 That is for a MAF (mass air flow meter), the original post was about a MAP sensor. Quote Link to comment Share on other sites More sharing options...

Anthony_piselli Posted Monday at 04:56 AM Author Report Share Posted Monday at 04:56 AM Going back to this, your right on the V10 not being there, problem at hand is the ECU isn't letting me calibrate the map sensor because I'm not within a certain altitude range, I have 2 old v44 ECUs I tested the other one calibrates fine. Maybe an internal barometric pressure sensor issue? Quote Link to comment Share on other sites More sharing options...
Adamw Posted Wednesday at 12:48 AM Report Share Posted Wednesday at 12:48 AM What is MAP and BAP reading with engine off? There were 2 different BAP sensors used in the V series, a common type and an alternate one for the potted marine or PWC ecu's. You could try switching to the alternate calibration in the >ecu settings>configuration to see if that is your problem. Quote Link to comment Share on other sites More sharing options...
Anthony_piselli Posted Wednesday at 07:52 PM Author Report Share Posted Wednesday at 07:52 PM Intresting, I fired up both v44 ECUs and one calibrates fine with the standard bap but the other one calibrates fine with the Marine bap. Both after calibrated are at 98kpa map, 0 mgp. So that fixed the issue Quote Link to comment Share on other sites More sharing options...
