Ok here's my question, when I boost my Teggy what kind of engine management should I use?? I want to be able to control the fuel flow on the fly. Im not sure but I dont think that the Hondata can be changed. Should I get a hondata, Apexi Boost Controller, with some bigger injectors and leave it?? There are so many products out now, ive only heard good things about Hondata. I will probably be running 8 psi of boost at the max and not very often, probably 2-5 psi for daily driving. What would the F.I. genuises recomend???

 

Standalone

 

2~5 psi? why bother.

A Zdyne will let you "tune on the fly", but thats only for OBD-0 cars

 

why would you want to control fuel on the fly. once you tune it you leave it. the only thing you would want to change is your timing and that is only if you plan on running a higher octane fuel.

 

What he said..

I belive Haltek let's you tune "on the fly", but again, I can't see why you'd want to do that once you dial your setting in on a dyno.

 

Tuning on the fly = KABOOM...

Once it's tuned nicely, leave it... The ecu will control ups and downs in fuel delivery thereafter... the last thing you want to do is upset a good fuel map and detonate !

Why would you want to run 2-4 psi ? That's barely enough boost to create the power to overcome the manifold restrictions ! AT least 6pai dude !

Wow 2-4 psi will give you a whopping 30-40hp? Why even go turbo?

 

Not even...

 

I just dont see the need to boost 7-8 psi in Atlanta traffic everyday. I have a 95 so it has almost 100k miles on it after I get boost I want to put off detonation for as long as possible until I have to rebuild it. I guess Ill go with Hondata dyno tuned and leave it. Any recomendations on good boost controller and turbo timer?? Thanks for the help.

 

You will once your boosted

 

I don't think you will need a boost controller. You can't go lower than what your wastegate is set at anyway. If you want one - Manual:Turbo XS or Joe P, Electronic: Profec B. As for the turbo timer: Sit in your car for a minute or the cheapest one you can find.
BTW, 5 psi is not a waste of time. I made 215whp at lower than 5 psi with A/C. That is on a GSR as well.

 

215whp with 5 psi ? Is that peak Hp with steep curve ? What turbo were you running to produce those numbers on only 5psi ?

I don't have a scanner so I took a pic with the digi. I did it on high quality so hopefully you can see it.

HKS/Garrett GT25 ball-bearing with Apexi intercooler, no boost controller.

If you only want 2~4psi just eat a lot of bean Burritos or chilitos from Taco hell and then fart while driving with the hatch open. Your butt dyno should register a 50hp jump. If you you feeel 100hp I would suggest pulling over and changin' your drawers.

 

Would that work if I hooked up a tube from my *** to the intake manifold? Any ideas on how to richen the mixture with this method?

 

Kepp your foot out of the gas, don't beat on your car and you'll hardely see any boost over 5 PSI. Unless you're using you're using one of those teee-tiny turbos that hits full boost at like 2000 RPM. If you want the extra power, but don't want it all the time get some N20.

 

Put off detonation? You talk like detonation is an inevitable part of owning turbo. Regardless of the age of your car and how built the engine is, detonation will destroy the engine. You don't build up engines to handle more detonation, but to handle more boost.

Get your car tuned correctly and your car will not detonate at 7 psi. Your car could detonate at 2-4 psi too if it's tuned incorrectly.

Also, 2-4 psi will result in a pressure ratio that will never come close to the peak operating efficiency of most turbos, so you really aren't taking full advantage of the turbo.

 

Yeah I hear ya. I guess I was a little too worried. Once I go boost my wallet takes a big hit, and I know that a rebuild is in the future I just dont want to have it be in the present. So custom turbo kit,bigger injectors, boost controller, hondata, boost gage. I should be set then right?? What about a FPR ???

 

And someone who can tune the wot and part throttle fuel maps.

If you're worried about the engine, make sure the engine is up to the demands of being turbo'd and have it chk'd out.

 

get that bitch tuned for sure and youll be fine! Pistons, rods, and a block guard would be good for ya too when you really want to up the boost

 

i made 209whp w/ 5psi. i dont like the amount of tq it gave though.
