Saab 9000 turbo engine ECU 

Up for sale is a Working, in excellent condition Saab 9000 Turbo Trionic ECU. Part number-- 4301909

This is original to 1995 9000 CS light pressure turbo. 

Unit is used, & comes with a 30 day functionality guarantee. Trionic ECU failures that will cause a no-start condition are not very common, but they do occasionally occur. More frequently however the mosfets for the BPC (boost pressure control) DO frequently fail, which will cause you to only get base boost and nothing but that.  If you have replaced your BPC, and still don't get boost - very likely your ECM has failed it's BPC mosfets!  Occasionally these control units will also develop a problem where they will throw erroneous check engine lights.  If this happens, replacement is the only option.   Interestingly, this ECU does not use it's boost control function as the LPT cars do not use a BPC (but have all the wiring, sub systems, and physical parts in the ECU to do boost control, and this control unit does have the functionality if reprogrammed with T5 suite!  Therefore it has totally fresh never used mosfets!  If you want an ECU to do tuning T5 suite tuning with, this is a fantastic unit to do it with!  If you just want a stock replacement, this is also a good unit.
