Dude, stop. Of course I know all this already. I've tuned a few Evos in my day.

And in this instance, obviously everything was not all right. A dedicated low octane map like Mitsubishi and every other reflasher uses would've likely saved the car from too much boost.

Are you also trying to tell EvoM that at altitude you can run the stock turbo wide open as long as there is some race gas in the tank? Don't believe that.

Again, this isn't flaming, its black and white fact and tech talk. Bottom line is that the boost increase killed the engine. Had it stayed in the boost parameters it was tuned for, this never would've happened.

I hate it for the thread starter that he lost his engine, but hopefully by posting this, others will not replicate his mistake.

 

Sorry, it's a bad idea to ASSUME anything like that is safe. The ECU will pull timing but if it is severely lean and you crank up the boost the ECU will not pull enough timing to keep from doing damage. A good example is the original poster of this thread that was also told it was safe....nope.
I've been tuning motors for many years now and there are just to many variables to assume something will work. Monitor it first with your wideband at the very least for a few runs.

 

Divulge secrets? Open source = the death of secrets. And if anything, the maps I've seen from that camp give safe tuners a road map of exactly what not to do.


Are you trying to get me to LAUGH MYSELF TO DEATH?!? Because it might work.


Warr, you're out of your league in this discussion even more than I realized. Learn to tune yourself and reality will hit you like a ton of bricks.

 

But it wasn't severely lean. It was tuned into the mid-to-low 11s.

Yes, Noize, I can run the turbo to its max on race gas at altitude - it doesn't matter. It just doesn't make as much power due to inefficiency, but it doesn't randomly blow the motor.

 

Sorry, Noize, but you really just don't get it. I do know how to tune myself and have done it for years. I choose not to mess with other people's cars, and I relinquish the reins to al for my own car, since he has more experience than I do, but I still know what's going on.

Laugh yourself to death all you want, but there is a part of this you do not yet know. It's fine if you think that due to looking at Al's maps you think you know everything, but you do not. In fact, it's better that you think you do...please continue in that line of thought - it's good for us.

 

off topic but you have buschur racing stage 5 i believe your sig said and your times are mid 12's?

 

 

It's got to be the heat, it's killing times across the country

 

Sorry to hear about the car.....if it went boom clank clank and wouldn't start that's definately a big motor issue. It won't clank without very bad things happening.

27PSI is alot of boost but it should be safe on 110+ octane. That is unless your car was damaged by poor tune prior to actually getting a professional tune.

What were your 1/4 speeds?

 

I was ther too ran my car bad clutch 20 psi with gt35 turbo and lightly tund aem ems on pump 93 gas only ran 12.9 myself after that it was down hill. clutch wouldn't hold. but as far as ur car hope theres nothin wrong alot of people said the track was sh*ty and no one was gettin traction that could be for the slow times carzy thing is we had the quickest times as far as street cars there. only car i remember running lower was a full dag camaro on slicks. think his best was 11.2 but good luck with ur car you'll have to let me know the results of the tear down

 

8 sponsors, self-proclaimed "packages" running low 12's.

broke college kids working with scraps and running 11's with less invested....Nuff said :laugh:

 

I know drag racing is fun....but on an overly hot day.....why even put your car through that kind of abuse? Especially since you pretty much know you won't pull the best slip you could.

 

day was very cool out maybe 75 with very little humidity was a good day to ran considering its been is the 90 and 100s lately

 

trust me I know were ur coming from had to save for three months just for a clutch so 11s are not outta reach after a dyno tune
