lookin for options and opinions.car is a 53 sti engined wrx with full 3inch exhaust,gt30 hybrid,cone filter ect.open source mapped.aggressive launch control required?? as cant get the turbo to spool at launch(4psi)any advise more than welcome.

 

Syvecs is the way to go. I had ecutek on classic, but didn't have launch control as can't get it. Now on syvecs, so much better, and can have maps of your choice. I have 5 so far, and loving it.

But then again depends on how big your pockets are.

 

been havin a look at the new alkatek set up.looks impressive.

 

hydra nemesis ems are good anti lag and launch control and mafless not that well known but good

Alkatek does look good. It's cheaper for a start, I think they are trying to come inline with syvecs.

Both are good ecu's. Beauty of them is mafless.

Give Simon jolly green monster a call, he'll help you out a bit more.
