lmao @ the whole road tuning thing, which to me is just retarded. Had you have been properly tuned on a DYNO by a good tuner it's very likely you wouldn't be experiencing these problems. Also you stated in your previous post that you notcied you were pulling timing at your track events but you just ignored the problem? WTF?! HELLO RED FLAG! Sounds like maybe you did want to blow your engine up!

 

I'm glad at least one other person understands why flashes are not all they're cracked up to be.

 

What people don't realize when they put on manual boost controllers is that it totally bypasses the stock boost control system. The stock boost control system has a safety feature built into it! If your engine is seeing too much knock, the ecu will cut boost to save your engine. So putting on an MBC bypasses a safety feature of the ECU!

 

So your saying that I should get a tune for my car probably so I dont blow it up? I always thought mine had problems only running an 11.5 at the track. It does make alot of noise too. I never had it professionally tuned at all. Here are my mods

Stock Head
HKS 272/272 Cams
Stock Block and internals
Shearer Header
Shearer O2 housing
GT35R
3" turboback with no cat
Rochester 72lb/min injectors
Aeromotive Fuel Pressure Regulator
Aeromotive A-1000 fuel pump
-10 AN Fuel feed lines
8 Gallon Fuel Cell
ATP Fuel Rail
Buschur Front Mount Intercooler
Custom lower IC pipe
Custom upper IC pipe
Custom Intake
Magnus Motorsports Intake Manifold
HKS SSQ BOV
Zeitronix Wideband AFR Meter w/ EGT
Hallman Pro MX Manual Boost Controller
AMS Alchohol Injection Kit (Running Methanol)
Full 10-point rollcage (6-point Belts, Window Net, Driveshaft Loop, Scatter Shield)

Im starting to wonder if I should get a professional tune. I think Ill wait till I finish the mods though what do you think... is it neccessary to do it right away?

 

I am picking up on your sarcasm My main point is for the the owner to be more knowledgeable about their car and modifications. In my case I was just lazy. I built one hell of a 240sx with SR20DET making good power. Did everything myself and the car was a beast. The problem was the old chassis (it was a '91) and problems with the chassis not being able to handle the power.

After I got the Evo it was so easy to say "I'll add that later" or "I'll get to it eventually". "Eventually" has now arrived.

I know you can tune your own car and I support that. (If I didn't need the OBD-II port for emissions I would have gone with the AEM EMS also) I plan to tune my own car now through the UTEC so I don't have to deal with this crap again.

You are the greatest. And your right I should have asked you for everything. You are soooo smart.

Pulling timing and adding fuel is part of the coolant enrichment process that the ECU executes when the engine temps/combustion temps get high so to answer your question "yes I did ignore it since that is a function of the ECU" but if I had monitored the car maybe I would have seen some knock activity.

If you look at the amount of people running flashes (tons) and the amount that have had problems (few) then you will see why a lot of people using them. It was never even determined if my flash caused the problem.

MY PROBLEM WAS:

Knock, knock
whose there?
dentionation?
detonation who?
BANG!

 

I just get bored The UTEC is a great tool... thats what i used all last season. It is very user friendly and makes it hard to blow up your car. Youll like it.

 

i'm one of those "weirdos" who will keep their car at stock power levels (for various reasons). so at least i won't have to worry about that stuff. but, since i DO care about accelerating and braking while TURNING, my first mods are going to be front torsen diff and brake pads (no gauges needed). i won't lose sleep if i don't have 350 awhp.
good luck in tuning.

 

I care about accelerating also Thats why I did all that crap.

And that dudes joke is pretty funny... I like it.

 

Nrcooled is there any chance you oil pump caused this? You said you had knock was that a knocking sound or was there something telling you your engine was getting knock? It just seems there have been alot of blown engines from oil pump failer.

As for the utec you can still blow your motor with one. There is a local guy with a evo that just blew his with a utec by tuning it himself. Most people shouldnt try to tune there own unless they know what they are doing. Its hard to hit every cell with just road tuning. It may be that you hit one of those cells that was not tuned when your motor went.

 

Its not hard to hit every cell with road tuning. I would always rather tune my car on a track than on a dyno. On a dyno you dont have any real world characteristics. Yes you would need to do a minor amount of research. If you cant figure out how to tune your own car with a UTEC you probably shouldnt get one at all. I believe anyone that buys any type of EMS should be able to at least make minor tuning changings by themselves and know what those changes are doing.

The UTEC lets you use the stock ECU to control everything if you want it to. You can easily find logs and logs of peoples cars, thier timing, boost, AFRs and everything. On top of that it has a very easy to understand knock parameter. If the car is knocking... let off and figure out why. It is all extemely easy stuff.

 

don't get defensive dude, I'm just stating MY OPINION that road tuning is a cheap yet UNRELIABLE way to tune a new expensive car. I could opt for a cheap and "effective" flash but I personally would feel uncomfortable doing this on my brand new car (IX soon). Everyone is different. TONS of people get mail-ins and custom road tunes and are happy with them, and make good power. My point is road tuning and mail ins are hit or miss, you're gambling hoping down the road you wont have problems, thus being unreliable. I was just saying dyno tuning is safer and more effective. However in your case it's clear your problems are mainly attributed to apathy and neglect of your $30k car! SHAME ON YOU!

 

suks big time...

 

Just out of curiousity, how much has the car, mods and repairs cost?

 

Great post. Way to make a positive out a negative.
