Engine Management

firebad · 10-15-2008, 09:30 AM

Why haven't any companies stepped up yet and produced something our cars can use?

There's gotta be more than enough demand for such a product, there's a lot of modded tsx's out there and you'd have the market cornered on it.
Without having some kind of reliable tuning method I won't add anything besides an exhaust and intake.

As soon you start altering i/h/c/e/im etc...you start changing how your engine breathes.

Hopefully hondata or another company will step up.

A 400hp turbo tsx would be lots of fun for a daily

Same thing i was thinking

400hp on a fwd is not that fun for daily

firebad · 10-15-2008, 10:26 AM

I understand that 400hp is way to much for the street, I was just trying to get my point across. I would be looking for 280-300hp and the flatest torque curve possible.

Then look into DAYTA's posts and read up on his supercharged 06. What you're describing exists; I've driven it and ridden in it recently, and it's nearly ideal for daily driving... 282whp 212tq. It's the setup I'm looking at for my car next year.

EM is out there. It just takes a lot of work and effort.

With the "out of the box" chip for superchargers, its only been tuned for 1 engine, every header, exhaust set will screw with the a/f ratios, and wouldn't risk the detonation.

I think i saw his graph, and his a/f ratio and it was lean in a bunch of areas. Not the best thing for a daily on pump gas.

Agree.

However, the population of modded TSX is still very small compare to Civic or RSX for example. Hondata has some great products for these car in terms of reflash or tunable ECU solution (K-Pro/K300), but there's a few obstacle for TSX because...

1. DBW is still too new for them to figure out HOW to permanently overwrite stock ECU command...
2. Sales profit might NOT recover the R&D costs...

The only good news right now is there's possible 05 5AT reflash soon, and possibility of K-Pro for TSX in dual ECU format.

Just because there arent any affordable EM solutions out there, doesnt mean that they dont exist

evertp1 · 10-15-2008, 02:25 PM

we can use K-Pro, but there goes our gauges
a Greddy E-manage Ultimate can be used as a piggy back
or do a K20a2 or a3 head swap from a 06 and older civic/rsx head, and buy an AEM EMS plug and play

nyc06tsx · 10-15-2008, 02:27 PM

i heard you can use the e-manage to control your ignition, and fuel but your vtec wont work..

wierdazndude · 10-15-2008, 02:28 PM

i know this is a common topic but why havent alot of people switch to K20 heads and try turbo with Kpro?

Well, never said none are existent. But I'm sure no one would like to pay $20K just for ECU like those in a race car.

If you are really delicate to do that swap on a TSX, might as well go for 07+ Si Sedan/CSX Type-S.

There's too much rumors around, he heard this and he heard that. It might work on cars w/ lots of budget like DAYTA, but he went thru alot of trial and error to reach this state and it's still NOT completely user friendly. If Greddy rep can not guarantee it works for TSX, I will take it as a NO because last thing you don't wanna happen is blown engine.

If it works you will see one on the road/forum already. You can be the first one to try getting a K20 heads/ K-Pro and Turbo and see if it works on your car. Will + REP you if it succeed.

That A/F plot was taken a while back at a dyno using an exhaust sensor, meaning the readings would show my A/F ratio to be leaner than what it really was. If anything, I believe the Hondata S/C reflash adjusts the fuel mappings to have the car run richer than stock for the exact reason you mentioned (different air flows based on different exhaust components). In fact, I was running so rich that I blew out my RT cat.

Since then, I've installed a AEM UEGO wideband O2 controller/gauge that gives me a much more accurate reading since the sensor is mounted directly into a welded bung in my CT header. I've monitored the AEM gauge, and at full boost (8psi)I'm at mid-high 11:1 ratios which is just about perfect for a boosted application.

That said, I do agree that a customizable tune option for our cars would yield far more power. I bet I could get close to 300whp with a decent tune.

I guess ill just be a guinea pig and try it. Ill let you guys know.
