K24 with K20A2 head + Toruku cams + SRI in RSX-S

[Scourge]

Well, I hadn't planned on modding my RSX-S as I have a K-swap (into Del Sol) in the works. But I blew the engine so I'm here for a bit of help.

Anyway, head survived. Got a stock TSX bottom end. Put Toruku cams on while I transferred the head over. It's got the RSX-S VTC cam gear (50 degrees?).

Everything is pretty much stock outside the engine. Stock exhaust (02-04). Only have a SRI because I didn't want to cut up my fender well covers.

Car runs but the stock TSX calibration feels sluggish to me. Does anyone have any suggestions? Or even better, a calibration? :D

It needs to be tuned on the dyno.

post up a datalog and your calibration , lets have a look.

Might have to wait until the weekend. My oil seal behind my crank pulley is leaking. I'm bringing it in to have the seal replaced. I don't feel like pulling the engine agian. :)

Okay, attached are various datalogs driving around this evening.

I hope I did everything right. I put it in open loop and had the MIL flash on knock. I did see it knock a bit but not too bad.

Not all driving was aggressive in case data is needed for non-WOT driving.

dude , your last datalog , the knock count was more than 6000 , lol. not good.

heres your calibration updated by me , now go do another long datalog like you did before , this time , in the datalog somehere , get the car in 3rd gear at 2500 rpm , floor it , and dont let off till 8200. make sure its in open loop the whole time.


i think most of his knock can be attributed to the 17:1 AF ratios or more , lol.

Discovered the cause of the "knocks". Had valve lash. Engine sounds and feels a lot better on various stock calibrations. Hardly ever see the MIL light flash now.

Well, I'm going to have to start fresh. Haven't had a chance to datalog yet.

have you checked Valve to Piston clearances? I think using a stock tsx .kal with toruku cams (street? or road race?) & stock exhaust the car will definitely be a dog

Was it too tight or too loose?

[Scourge]

It was too loose. Barely any gap now and it sounds/feels good. Weather is nice again... Looking for a nice calibration again. :)

I haven't gotten any new calibrations yet.

Oh, and it's the street cams...

[cranny]

use the same kal you had , just datalog again and post it up.
