1991 laser ecu questions.

Alright everyone. I have a 1991 laser 2.0 na im going turbo in the spring and im lost and have no idea what to do for a ecu. I know im goodg with dsmlink. How does it work and what do all I need for it?

Thanks colt.

Your going to need a turbo eprom ecu, it will need to be socketed and then have the link chip put in. You could also go with a non eprom turbo ecu and have it converted to eprom.

I don't think that n/a cars had a knock sensor so you will have to wire that in.

How much should I be looking at spending on the ecu with the eprom and the link chip put ?

Well, it ended up costing me about 1500 total make the change and rebuild the engine in the process. That said I also wasn't planning to use dsmlink to tune it so I wasn't in need of an eprom, just got a regular turbo ecu to put in. other than the ecu you need to replace the maf with a turbo one, or do something else such as convert to a 2g maf, etc. The na does not have a knock sensor so you'll need one of those too. You should also try to find a boost control solenoid even if you plan on controlling boost in some other way. Sometimes you'll get a CEL for it if you don't plug one in. I used a mbc on mine so i just strapped the bcs under the dash next to the ecu so I didn't have to use as much wire.

There's a number of other things involved obviously, but that's the bare-bones of what you need to please the ecu.

ive been doing some reading, and what ive figured out is yes i need a turbo 1g ecu that shouldnt be to hard to track down. but im going with the dsmlink v3 along with the gm maf, im gonna have to go with it, i just picked up a precision 6152 turbo. picked up the dnp exhaust manifold, and a bjs intake manifold. now time to find a block, maybe a built one. i have my eye on one on craigslist with a manley crank, rods, and pistions in it already. 1200 bucks im thinking about getting it this weekend.

oh and how do i go about putting in the knock sensor?
