I've currently got the MS controlling injectors, the O2 is plugged into it as is the coolant AIT map etc. I'm not currently controlling the idle or spark via MS. After tiring of playing with the settings to kill my low load stumble i decided to hook up the TPS (which I'm ging to replace at some point with a proper analogue one!) and I've got 2 wires from the MS from the TPS, and I can only find 1 wire in the MX5's loom...

I've tried combining the two which obviously didn't work, and having just one of the two didn't work either, I need another wire on the MX5 loom obviously, but which one is it?

Next question, I quickly plugged in the coils, just to check my modifications were working, and that I didn't need new coils . Started 1st time, but it sounds like the car is missing i.e. running on 3 cylinders. I'm currently using Kingof's MSQ, abit with a mildly modified VE table and the dewll settings set of my 1.8 coils (4.0 crank dwell, and 2.2 running) could the spark be washed out due to too low of a dwell setting? or is it just my spark tables which need sorting? etc etc

As you've probably guessed, tuning is a very new concept to me!

Thanks!!

 

Welcome to the joys of tuning.

You don't need the TPS to overcome your stumble problem. I'm running my car from the MAPdot settings and I don't have any stumble at all. You can overcome your stumble with tuning as well.

If your car sounds like it isn't running properly with the spark, check your connections and then play with a few settings to see what happens. Kingfl337's spark table won't be what's causing your problem.

 

ha ha thanks!

Sorry, I wasn't looking at the TPS as a way of sorting the stumbling, I just wanted to move onto something else Ideally I'd like the TPS connected to the MS then I can use the flood clear feature and stuff

will do thanks Aussie!
