Has anyone used gear corrections with ignition timing to lower power in the lower gears for traction?

Car makes 400whp on the waste gate (15lbs) and I don't wanna go smaller because I lose response and its harder to keep boost consistent up top with smaller springs

Quick question sir, are you still running a 2 bolt 38mm wastegate sir? If so, do you experience any boost creep with your setup? I know that you have a larger turbo than mine and I was just wondering if you have any problems keeping boost steady with the 2 bolt 38mm wastegate? I am pretty sure what everyone is telling me is correct. I am running little boost and conservative timing on my very efficient turbo and that is why I am experiencing boost creep. I am also running a ram horn manifold and a 2 bolt 38mm wastegate and I am trying to gain knowledge for myself. Thanks in advance and your input is greatly appreciated sir. Sorry for the thread jack sir.

LightningTeg

No I dont. I taper my boost controller duty cycle down a bit up top to keep it flat

Thanks for the input sir.

Looks like your injector are maxed out.

A little bit

Oh that must be nice... lol

I dont understand why you are against boost by gear when you clearly have ebc duty left. You could run a smaller wg spring allowing less boost in lower gears and still run 28psi in the higher gears, just with a higher ebc duty. Its the best of both worlds. Believe me you have alot more boost range left than you realize. I have a 5-30psi range with my setup.

I've tryed it with a 7lbs spring and it hooks in 1st rolling into it and 2nd no problem but the boost comes on slow and builds slow up top as small springs do. I spent days tuning trying to get it as good as it can be. Especially up top it gets very inconsistent

Make sure the ebc duty is 100% under the boost target. If you are running a static duty to make x boost the entire time, thats not spooling as fast as it can.

LightningTeg

Yes fast spool is at 100%. It just doesnt work as well.

Is the solenoid acting on the top wg port? Or is just on the side wg port and top is open.

You can try a 4 port solenoid that will switch all boost reference from the bottom wg port to the top wg port. That will force 100% of the boost pressure to keep the wg shut.

I didnt use the gear ignition correction to lower power in the lower gears but my tuner pulled timing out in 3-4 gear initially for the first couple passes with the car so we could read plugs and check for detonation with a real load on the motor. Picked up quite a bit of mph when I put the 2 degrees back into it in 3-4 gear. It will definatly reduce power and should help with traction

Did you ever find out why your car blew up?

Pretty sure boost spiked to 33 or 34 pounds and just blew it apart. thats 700whp on my turbo and stock sleeves no likey
