Cheapest engine management
 

What would be the cheapest way to get my car running off of boost without spending 1k - plus on cpu parts. I want to run a max of 7 psi on a 95 del sol vtec.

thanks

jeff. very coo. but i am wondering, do you need to use those boss 480's?

Re:Cheapest engine management
 

300 is more than you can pick up a MSD btm and used afc for....

thats basically like what they use in the F-Max kits right? i heard alot of people ditching that setup but how do you feel it works?

i think the cheapest possible without building your own controller would me the SMC+ for like 119 then a set of 450 cc injectors for 50 or less... this gives you fuel adjustment only in 1k increments and does nothing to control computer advanced timing in the upper rpms however so i wouldnt run this alone with high boost. '

with an FMU you also have to add a fuel pump so thats about 200 bux for both but isnt tunable except for changing the discs

also i wouldnt go on any onld a/f ratio gauge alone, only use that as a base then get yourself on a dyno to tune with a wideband. very much worth the money....

Well if your car was OBD0, there is a current solution http://www.ghettodyne.com/

Supposedly in the next release (soon) it will be supporting boost... which kicks ass! And is the fuel mgmt setup I'll be using.

My bro has one of those. The full setup will cost more than 1K. However, they're farily robust, and offer great bang for the buck. It can get rather pricey after the base unit though.

Megasquirt sucks, a friend of mine runs it on his turbo Volvo, and another friend runs it on his turbo Rabbit GTI, neither has ever run right, and we've tuned the ---- out of both of them.

SDS is pretty much the middle. It's not as pricey as the TecIIs and TecIIIs, or any of the other high end stuff, but it works really well. The downfall is it doesn't do datalogging which is REALLY nice for tuning.

Anything else costs to much.
