STEVEN BORNHORST Posted September 25, 2021 Share Posted September 25, 2021 1995 2.2 Subaru Legacy engine has transplanted in a VW sand car, I have the 2.2 engine running with the stock ECU although with all the car gone but the engine it is in a limp mode at 3400 + RPM If there is anybody that knows how to circumvent all the limp modes. $$ the ECU is AB414 5602 / It has the gray plug. It idles good and runs good until limp mode. If anybody can help $$ will be appreciated very much. Thank You Steve Quote Link to comment Share on other sites More sharing options...
wtdash Posted September 27, 2021 Share Posted September 27, 2021 What are the codes ? Common issue is a cracked Knock Sensor, esp. on the <'95 models. Quote Link to comment Share on other sites More sharing options...
3Pin Posted September 27, 2021 Share Posted September 27, 2021 do you have a VSS speed sensor installed? Quote Link to comment Share on other sites More sharing options...
STEVEN BORNHORST Posted September 28, 2021 Author Share Posted September 28, 2021 Have VSS from Small Car Performance, I will check the knock sensor. Haven't been able drive it long enough to get any codes, any other ideas are very welcome. Quote Link to comment Share on other sites More sharing options...
lmdew Posted September 28, 2021 Share Posted September 28, 2021 Do you have the connectors in the harness to put it in the diagonsitc mode? Quote Link to comment Share on other sites More sharing options...
STEVEN BORNHORST Posted September 28, 2021 Author Share Posted September 28, 2021 OBD 2 Is wired to the ECU Quote Link to comment Share on other sites More sharing options...
heartless Posted September 28, 2021 Share Posted September 28, 2021 there are 2 pairs of single wire diagnostic connectors on older Subarus... one pair is green, the other is black.. they are there for a 95, I know this for fact since I owned one. they should be UNplugged for normal driving mode.. 95 was a voluntary OBDII setup, Subaru did not have to do that, but they did.. they also left the diagnostic connectors. 1 Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 28, 2021 Share Posted September 28, 2021 I see you are local. We do offer a LINK ECU with adapter harness for the 95 and 96-98 cars. Would be far better than trying to use the factory ECU. GD Quote Link to comment Share on other sites More sharing options...
