Trying to decide what to do?

I had my car tuned last year. I was never really satisfied with the tune idle is high lean at idle etc. Well I had to replace my fuel pressure regulator and now the tune is way off idles good but is rich as hell cruise like 10.0. Right now I have a sct chip.

I am thinking about going with a megasquirt system. I am trying to set up having Kurgan tune my car in spring. Just trying to see if its worth the cost to go megasquirt. The one thing I like is if I make changes to car I can make simple adjustments to get it right. Where with the sct I have to have someone tune it.

did you check the pressure after you replaced it ? if you are running that rich i would think you pressure is to high.

It's up to you to figure out if it is worth the money for an an aftermarket ecu. it seems like it can be cheaper in the long run but takes more work. Sure you can get it a unit that plugs into the factory wiring harness and a base tune for a mild car, but to do it right you will want to go through the settings of it to make sure it is right on your car.

There is loads of info on the web about how to do everything. it is like information overload, lol. do some reading.
Megasquirt MSEXTRA Manual Index

I will say if you decide to purchase one, i was very happy with MegaSquirt | Engine Management System | Electronic Fuel Injection - as my reseller. Their email support gets back to you within a day. Matt answers questions in the megasquirt section and on Megasquirt MSEXTRA / MS3EFI • Index page.

i am happy with my ms3x. my second choice would be the new pro m system but it is way more money.
