Losing PW Signal
Hello me and a friend have put in an RX7 13b REW Engine (with Single Turbo) in a Austin Mini.
we have put together MegaSquirt v3.57 with extra card for rotary engine.
everything works well except 1 thing.
we keep loosing the PW Signale (well it drops to 0 after a short time on idle run)
at first we thougt it was the TPS but we have checked it and its smooth.
then we started looking for leaks but noone of the vacum is leaking so it do not pull false air (we even checked with start gas to see if the RPM was responding to it but everything seems tight and airproof).
last time we started the engine (earlyer today) it was running smooth until 71c and the engine was out of warmup enrichment after that it seems like there is something that cuts the PW signal.
so i was wondering if there are any of you guys that have had the same problem?
(BTW. im not 100% sure if this is the right place for this post so i also posting it at Single Turbo forum part. so just delete it from here if im mistaken)

This is definately the place. Be patient is my advise. People in this forum will help you but the answers dont always come easy or quickly.
Im not experianced enough to help your situation, but someone will. It sounds like you need to go back and check some of you basic settings. Like when your warm up ends, you have nothing. So the warmup is what you are running on.

it gets out of the Warmup so thats not problem that ends at 71c and we are getting past that point and the warmup is ending as we run it on megatune all the time to calibrate and check for errors.
but i was wondering, is it the Crankshaft that sends the signal to the megasquirt who triggers the pw since they controll the injectors? it seems to me that thats what they do but not 100% sure so if anyone know we got atleast 1 step to start en errorsearching.
