g4+ atomizor Posted March 27, 2017 Report Share Posted March 27, 2017 Hello I am currently wiring in an atom on a neon 420a engine and was wondering if and how anyone has gone about the crank trigger setup. will it require a new trigger wheel and new sensor or can stock sensor be configured? Also is it possible to run engine off cam signal only? Is that a bad idea? Any input would be much appreciated thanks. Quote Link to comment Share on other sites More sharing options...
Adamw Posted March 28, 2017 Report Share Posted March 28, 2017 I found we have a record of the stock trigger pattern for this engine and it is very odd. I dont think we have a mode that will work with this. You cant use the stock cam sensor only unless you could change the number of teeth to something more useful.I dont know these engines well, it may be that some parts off another engine can directly interchange but if not the easiest option would be something like a 12-1 wheel on the crank. Then you could either run it with just that or grind one tooth of the cam and use both for sequential. Quote Link to comment Share on other sites More sharing options...
UMSTunah Posted August 19, 2021 Report Share Posted August 19, 2021 Bringing this back from the dead... I see 2 PT Cruisers listed in g4x triggers...is the non 2.4 one happen to be for the 420A? Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 19, 2021 Report Share Posted August 19, 2021 Yes the PT Cruiser mode is for the 420A and ECC. Looks something like this: Quote Link to comment Share on other sites More sharing options...
