what miata?

what are u guys doing for crank signal??? a friend ask me to put MS on his 99 and not sure if i shout run a NA old school cam sensor. and take that plug out the back of the head. and what about the return less fuel system? im guessing u guys still run the stock ecu to run that. im looking for a write up but nothing found anyone got a link to a thread that could help or something.


thanks sebastien

Gonna have to search a lot and find answers. Here's the jist of it though:

MS1 + 99' = CAS

MS2 + 99' = Read factory sensors

I use a MS1 and a CAS on my '99. MS controls fuel and spark.
The returnless system matters not. Just add larger injectors depending on how much boost (power) you plan on running. Stock '99 injectors are good to 6-7 psi (barely). Above that you need larger ones.

oright thanks guys... the onlything is that the car is going to be boosting at least 15+lbs... its a built engine... i think it already has 440cc or 550cc rc's... whats the stock fuel pump rated to? and if it cant support what fuel pump to put in? can a 190 or 255 in tank be put in... sorry for all the questions never worked on 99 or a street car with returnless. on some of the race cars we run aftermarket regulators and run the return back.

anyway i will do my homework a little.. if got any sugestions chime in
thanks

Tell him to get a dual feed rail. While a 190 pump may be sufficiant, id get a 255 instead if hes going to be running over 15psi. And what pat said on the sensors.

I run an MS 1 with stock M1 CAS and Fuel pump. I'm in the 15psi range with one of our rails.
