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") only found in 2.0L and 2.4L 4cylinder Chrysler engines ? [wikipedia suggests] this 1.6L engine might be of the BMW / [Mini-Cooper] family - sounds like 60-2 is most likely than
- 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)
I gather any info available about this car/engine here -not a very common one.
Comments are welcome!
