1.6 MX5 enine tuning

[baz-r]

strip back all the unwanted engine manigment suff and fit megasquirt (set up right) would be the best bang for your buck.
and could be tuned to any future tweaks.

simply nothing beats the right mixture and timing every time that is the beauty of eletronics.

Stick with the stock system until it's on the road. The stock system will work with some mod so until you get to lairy cams you'll be ok.
To be honest I wouldn't waste time on Megasquirt. I've used it in the past, ended up costing almost as much as an omex system. Al & Bruce say its experimental. To experimental if you ask me! The msqt was unreliable, not easy to build or tune, few rolling road places will deal with it.
Car spent too much time with me trying to fix msqt faults and after two expensive recovery trips I bit the bullet and bought an omex.
The omex does what it says on the tin with no hassle. Not a single breakdown from the time it was fitted to the time I sold the car.

Never had any dealings with Megasquirt/ Omex.
Probably a silly question but why should one of these be used, what are the real benefits over the stock fuel management system (am i right in saying these are just standalone fuel management systems?) Are there additional features, easier for the home mechaninc to tune/modify the engine etc.
Just trying to get a better idea of these systems. Will try to do some research on these during the week, but would appreciate if someone could give me a starter lesson

When you buy one, does it come pre-loaded with base maps or does this all need set-up by an engine tuner first.

Im sure all will become clear

Less is more...

Yeah, they're both aftermarket engine management systems intended to replace your original ECU.
The benefit is that they allow you to completely mess up, erm I mean tune, your spark and fuel

Unless you're going to make heavy engine mods, go forced induction, or just like to spend endless hours tapping numbers into a lap top I wouldn't bother!

Saying that, I probably will replace my OEM ECU post-IVA, but mainly because I'm a bit of a masochist and like playing around with electrickery

I have lost count of the cars I have tuned and ended up over doing it. N/A wants to be kept to a mild cam, sensible comp ratio and a well sorted ignition/fuel set up. That way it keeps the all important driveability and remains useable on pump fuel. If you want more, turbo is the only way.

Just a thought,
My old Subaru Impreza WRX (as my avatar) had some fancy fuel management system and was pumping out around 350BHP, it had a "Dual map " setup where i could use on one setting for "Road" (mild boost) use and another setting for performance (WILD boost) including launch control etc .

Could something like this be implemented into one of these Fuel management systems that have been mentioned.
Would probably only realy be worthwhile if the motor was turbo'd .
