Hi all, Is there anyone attempt to make engine lean mount for RSX like those available for EG/EK? I like the idea of creating acres of space for turbo drag setup on RSX rather than go with the traditional sidewinder turbo manifold.

Since the weather has been getting cold now, my car needs more fuel so its running lean. Ive been hitting a fuel cut so Ive done some research and found conrads Air temperature compensation calculator and tried to use that but still no improvement. Maybe ive been inputting the numbers wrong in...

Whats going on guys? Im hoping someone can relate and help out.. My car is running lean during boost and hitting cut off since installing a walbro 255 intank My car ran fine on the stock pump with an inline 255 to supplement it on pump gas. Since the stock was replaced with a walbro intank and...

Hi guys been reading and done my searches on google and on the forums. My car is throwing p1167 and p0171. I already searched what those codes means but this sounds silly. I'm trying to figure out what is the difference between oxygen sensor Denso 234-9004 vs Denso 234-9005? The only difference...

I have dc long tube headers and the flex pipe is pretty thrashed and leaking, the code says system running too lean P0171 my air assist bypass valve is broken and I'm...

Hi guys, I wonder if someone could help me with an issue I have been having. It’s stumped quite a few people. Car: Honda Civic Type R EP3 2004 (UK), Rotrex supercharger C30-94 (FMIC), RC750 injectors, 3” exhaust, de-cat manifold, RBC, 74mm BC throttle body ported to RBC, built engine (10.5:1...

Sorry if this is a noob question, but I see people say it a lot and was wondering what this meant.

So I'm in the process of buying a 2004 JDM dc5, as it says the motor is a k20a2 with a k24a2 block the engine light is on and the owner says it's from lean mixture because he has a k24 block with a k20 computer and it only runs lean when it's in open loop. Could this be the reason why the engine...

I anticipated running a little lean after installing my raceheader. So I thought adding 10% fuel to the cai calibration for high fuel, and leaving my low fuel at 5% more on top of the cai precalibration (a total of +15% high fuel +10% low fuel). However I get cut off around 5,500 rpms with full...

Hopefully the title attracts others experiencing the same issue.... I plan to follow up in detail with results after the problem is fixed. Brief Details and Setup: -02 RSX Type S -K24a2 with Greddy Turbo Kit T517z turbo -Kpro -RC 550cc injectors -Walbro 255lph fuel pump -Stock Returnless Fuel...

EDIT: I've replaced/tested all of the following: Fuel pump, fuel lines, fuel rail, fuel injectors, spark plugs, ignition coils, TPS sensor, ECU, tune, o2 sensor, timing, throttle cable, vacuum leaks, boost leaks, and exhaust leaks. All have not fixed the problem. I'll start with my main fuel...

I've been having this problem for the past month or so now. 95% of the time I shift from 2nd to 3rd (half throttle to WOT...doesn't matter) my A/F spikes and hits lean cut. If it doesn't cut out it goes to 17.0:1 or so before it finally drops back down. If I granny shift it and accelerate slowly...

Driving home from work a couple days ago I got on it a little bit and the car was obviously weak, probably down 100hp. I next time I cranked it up I got a check engine light for "lean condition" and I took a datalog, with the car running way lean. I reflashed an older map from a few days ago...

So I just got k-pro today and did 45 minutes of running and adjusting. Before I lock the cams I just wanted to get things ball parked. I kept getting spikes in my datalogs that went from 12 a/f to 32:1 a/f when I let off the gas. Is this normal? I haven't seen this anywhere else and I added a...

A/F ratio goes really lean when high boost is creeping. I'm not an expert but I seen af on the datalog and I know that spike isn't good. I've read the instructions but its still not that clear to me. Any tips on how to adjust it?

Hello all, looking for a little advice. I bought kpro and currently only have fujita cai and magnaflow 2.25 catback. My plan was to run the k20a2 cai dyno tuned kal until picking up RH in the near future under the notion from other folks on here using it with no problems especially with a...
