I am wanting to get a better tuning option for my 91 spirit r/t. Although I blew away a new 5.0 a few months ago , my tune could definitely be better. I have ran a fwd performance stage 4 cal before and am now running a Paul V cal. Neither of them have been perfect although the fwd cal ran better at wot. I know boostbutton does flashable cals for tIII's now. I've read the long thread by DoubleD about his experience. My problem is I don't understand all that about tuning my own cals and it seems really complicated to me. Also, I don't know if my tuner would be able to us the mptune software or whatever it is to tune my car. Of course the route of going with a flashable socketed cal would be cheaper than going with megasquirt. I talked to my dyno tuner, Nigel, from Brutal Speed and tuning her in NC and asked him about it and he said he had worked with Megasquirt and was well versed in using it. He's is a very good tuner and the best as far as I can tell on the srt forums for the Nsrt4's and did a good job tuning my wife's PT Cruiser. I know the new megasquirt is suppose to be able to use many of our stock sensors. It can have a 4bar map I was told. I want my car to be rock solid on the fuel ratio. Stoich for idle, cruise and smooth deliver of 11-11.5 all throttle inputs whether part or wot when rpm and boost above 5 or so or whatever is correct on that, warrant it. My car currently has +40's and gt30 turbo running around 25psi boost with alky injection starting around 8psi. Rei, aka "Rattlesnake" on the forum, works on my car and has always done a good job. He likes the idea of megasquirt. Of course its up to me.
So, before I invest a hard earned $800 on Megasquirt and needed sensors, I guess my questions are:
Is it worth it using the new Megasquirt to have a smarter computer controlling the car versus the 91 SBEC?
Other than I know my tuner already is familiar with megasquirt, what other benefits would it have over other tuning options?
I know all setups are different but who has had any experience running the new megasquirt on our cars?
