First things first, I am very new to tuning turbo cars. Ive owned more than one vr4 but have never gotten around to heavily modifying one.
Anyway, Bought 659/1000 recently and have had the timing belt, water pump, balancing shafts, oil pump, engine seals, and drive belts, and some other minor things replaced. Since I got the car back from the shop, my idle has changed from 800 to 1050, and the car has NO power and the knock sensor (converted factory boost guage) is going nuts! I dont have a data logger yet, and am simply trying to get my car back to the way it was. I'm considering ECMlink v3 to start learning more about tuning, and possibly fix the car myself, as the shop I took it to screwed it up and cant seem to figure out how to reverse what they did to the car.
The base timing was set at 7 degrees, then to combat knock, was changed to 3 degrees base, and nothing changed.
Here's a list of current mods to the vehicle:
Recent new Evo III 16G turbo
Evo III high nickel exhaust manifold
Turbo back 2.5" custom exhaust with hi flow cat
Evo III turbo
Evo III exhaust manifold
socketed ECU with keydiver Stage II EPROM
The car used to reach peak boost of 13psi at WOT with little to no knock, now will start knock as soon as boost begins to build, even when I am only at 60% throttle.
Let me know if you need any more info. Sorry I dont have a logger yet I wish I could put up a log for everyone to see.
Thank you in advance for any help or input. I greatly appreciate it.
