I am working on a turbo 300 6 project and need some help on a megasquirt fuel map. I am a beginner at the whole fuel map deal, so I need a good place to start for tuning. I will be running 7 to 8 PSI boost max. I am using an engine I recently rebuilt, only has ~1,000 miles on it. Basically, I am curious if anyone has a fuel map that would get me in the general area to run this. Thanks!

 

You may have better luck on the Megasquirt forums if you don't hear from someone here.

 

I started a post on Megasquirt forums nearly 6 months ago and strangely nobody there could tell me anything. Thanks for the suggestion though. I have recently decided to not turbo, raise my compression a bit, and add a little cam duration. I ordered a MS to EEC-IV adapter on Saturday, should be here sometime this week. Anybody on here ever use one of them?

 

do you have megasquirt one or two?

first you are gonna need megatune.

here are a couple links
Initial VE Table Calculator
MegaTune for MS-II/v2.8

unfortunatly the table I put together is hidden away 1300 mile from here. I will see if i can make up a quick map.

 

I have an MS2. I used megatune and tuner studio, got close and one day I went out to start it and it gave me nothing but problems. Ran great one day, got nothing but misfires and popping out of the exhaust the next. Went through and redid my entire fuel table, got close, but thought I heard detonation when I hit the gas real hard, coulda been exhaust noise at the time. So I went back to the stock ECU. I have decided I am going to use my Eaton M90 on my engine, 6 PSI is where I'll start for boost. I just want to get my fuel system ready for the Eaton. I also encountered problems with MS2's timing advance deal. If I set it up to control timing, I will drive along and occasionally it will cut spark briefly, won't do it if I disconnect the SPOUT connector, so I know it's spark related. Also won't do it with the stock ECU. I have all the proper resistors in place to run timing control. I am in the process of converting to MSD ignition, so I won't need MS2 timing control, and I have purchased an MSD Boost Timing Master box, will get an MSD 6A hopefully soon. Figured I didn't need the limiter feature and it's cheaper.
