Summary of change:
'''Chrysler PT cruiser turbo project''' The plan is to install a low pressure turbo-system on the stock engine. Control with VEMS ECU - of course. ---- * Engine 1.6L inline 4 Tritec (T16b3) I guess * probably similar to BMW W10 used in Mini? * Crank : HALL 60-2 ? ** most likely NOT Chrysler Neon-like ("Neon / 420A") found in 1.8L, 2.0L and 2.4L 4cylinder Chrysler engines [http://en.wikipedia.org/wiki/Chrysler_1.8,_2.0_%26_2.4_engine wikipedia suggests] this 1.6L engine might be of the '''BMW / [http://en.wikipedia.org/wiki/Tritec_engine Mini-Cooper] family''' - sounds like 60-2 is most likely than. [http://www.minitorque.com/forum/f24/r53-oem-engine-management-discussion-questions-info-34983/index3.html nickbmw explicitely mentions] '''"the crank trigger is 60-2" ''' * VR : HALL 1/rot * '''Throttle: ETC''' (what kind? can VEMS control it?) ** most likely passive (and most likely 5A, VEMS bridgeoutputdriver can control upto 10A). ** However '''factory ECU might be unhappy if someone else is controlling it !''' ** to verify it is passive type: Measure some resistances eg TPS / TPS2 when throttle is moved manually and PPS1 / PPS2 as pedal is pressed. Or measure voltages if factory ECU is powering it. * factory knock sensors * no VVT (?) * Wasted spark ignition 2x2 (logic or dumb coil?) * Idle valve? ** maybe stepper ? Should be possible to control it either way. ** the worst case if no idle valve at all, relying on ETC (which is supported, but requires precise tuning for VE, warmup, ETC before idle tuning can even start) ** I would really '''look for idle valve and inspect the connector''' (how many pins, resistances, ...) * Temperature sensors? * automatic transmission ---- Probably we need to keep OEM ECU to keep auto trans happy, and other extra features. * "without MAT and CLT pullup resistor" would be appropriate order comment ** it is possible to remove those resistors with only endplate removed, best to not have them in the first place when the factory ECU is kept in place (which already applies pullup on these analog signals) ** it seems like the same T16b3 is revlimited in the PT-cruiser to 89 Hp (same engine in Mini-Cooper is 114 Hp ?). It is unlikely that factory-ECU + tranny would do anything nasty at higher RPM / power. However factory ECU might start to close ETC somewhat (on the other hand if ETC is controlled by VEMS, which is possible, the factory ECU might log lots of error codes: most likely would still maintain the required RPM/MAP dataflow to the tranny to allow operation). ---- '''Autotrans''' - which type ? (planetary gear ?) * shiftcut function will be needed ? (if yes => shiftcut signal needed) ---- I gather any info available about this car/engine here -not a very common one. Comments are welcome!
