Hi does anyone here use a Split Second piggy back unit?
Since i am going to be supercharging my 2.2L, I wanted to get the fuel system taken care of first. I did a little research and came up with 3 units and decided on the Split Second PSC1-002. It has a built in 2 bar map sensor that replaces the stock sensor, and it hooks up to a laptop. It will allow 200 cell value changes. My plans are to go with 24# injectors from a cavalier Z24, and see what happens from there. This unit runs approx $300 from split second, however you can pick up new ones on ebay every now and then for $100-$250 I got lucky and picked this one up for $110 shipped.

If anyone uses this unit Please let me know, it would be nice to talk to someone who has tuned with one of these.

i've used a the Subura program (eprom?) or something like that on my laptop. we drove once, recorded all data on a outragouesly boosted WRX, parked, adjusted fuel curve, saved. ran again, re-tuned, ran again, ect.

we never fully dialed it in, but it doesn't shoot five foot flames as often.
