Are you really using the stock ECU?

You need at least a P06, modified, and properly tuned... If you're boosting on a stock ECU, you may have damaged far more than your map sensor...

sounds like a boost leak to me, not lag.

I'm changing your thread title. It's not very descriptive.

I think it's probably a fueling issue over anything else. The stock ECU is trying to fuel for turbo, running injectors twice the size of what it's expecting. Basically, this is the equivalent of giving an 8 year old an overdose of caffeine and telling him to do differential equations.

[Accord R33]

i'm suprised it even idles with 500cc+ injectors and the stock ECU.

[deevergote]

That may be why he's saying it isn't running now...



We really need more details regarding the setup to know what's going on... but regardless, this is halfassing to the extreme!

But I read that if you disconnect the battery for 5 minutes, the ecu retunes itself!

Thats what ebay claims..
Is the op still around?

It does, with a stock or near-stock configuration. Turbo and larger injectors are a totally different story!

If the OP is still around, I hope they're reading this... and not sitting around with a blown engine.

Yeah, the ecu will not autotune a turbo configuration, just for clarification.

it was a fuel issue cause i started the car and squeezed the fuel line and it was at idle fine im getting way to much gas any ideas what kind of computer i should use or where i can get one???????

[myflycb793]

i didnt blow the motor and there is not really a place in my area where i can get it tuned i would have to drive or get it towed. i did disconnect the battery so the computer could reset any info on a computer or a place near me that does tuning i would be grate ful thank u all

Don't take this the wrong way, but you should have probably sat down and thought this out BEFORE your threw the parts on there.

At the very minumum, you should at least buy a chipped ECU from one of the members here, even if it's just a base map. its better than the STOCK ECU.

[deevergote]

Look up a shop in Woodbury Heights, NJ called All About Performance. It's not very close to you, but they're really good... and they know Hondas VERY well.

You NEED to tune the ECU. The stock ECU WILL cause damage. It has absolutely NO idea how to compensate for boost, and it doesn't know how to work larger injectors.

What you should do is return the car to stock until you get an ECU. As I said before (I think), you can get a P06 from a 92-95 Civic LX or DX. Have it modified, chipped, and tuned for YOUR car. A basemap is an easy way to blow your engine... but it will make it driveable to a tuning shop.




What I don't understand is how you managed to install a turbo without knowing that the stock ECU won't work with it... I don't mean to offend, but that's just baffling to me!

Just to make sure... you're not running 87 octane gas, are you? Not that it really matters with things being as messed up as they are at the moment... but that's a no-no for turbo as well.




Take the turbo off. Get the ECU. Put the turbo stuff back on. TOW IT TO A SHOP. Have it tuned.

If you can't do that, you can't afford to have a turbo car.
