Apologies in advance if this is posted in the wrong sub-forum, wasn't exactly sure where to post this.
Anyways, I have a 08 GSR SSS. I bought it almost a year ago, July 2020. Ever since I bought the car, I have had this "knock" or "thunk" sound coming from the rear of the car. When...
I have a very quiet knocking coming from the engine at idle in my 4b11 which I assume is due to the cheap 91 gas in my town. When the throttle is pressed from idle at 750 rpm or so, there is a super brief louder knock which is unmistakably fuel knock, but the knocking does not occur at any other...
Okay first off, i have a 2010 Evo X GSR. Mods:
MAPerformance o2 downpipe
OBX test pipe
Greddy single exit catback
Ultimate Racing UICP
Cobb Stage 2 LWG map
Comp Stage 3 Clutch & Lightweight Flywheel
I know what matters most is knock at WOT but im wondering is a lot...
So anyone who's tuned enough high horsepower Xs has probably run into this issue at least a few times. Personally, I come across a few cars like this every year.
I'm currently tuning a car with a big turbo setup making around 500whp. Unfortunately, it's one of those setups that the knock...
Hi Everyone, GO GO First Post!
I own a sexy black 2011 Evo X MR and my only mods are an ETS UICP and Cobb's v403 Stage 1 91 octane map. The vehicle has 20,000 km's on her and I've only launched her twice (both without slowdown message).
Lately I've been noticing that when I start to...
I have a 2008 gsr w/ cone filter, test pipe and custom cbe.
Obviously im new to this and can use some help..
I have been running cobbs stage 2 maps(pill removed) and was over boosting to 31-32 psi.. switched to lwg maps and now I underboost 14-16 psi from a roll at 4k in second. but if roll at...
Basically i'm getting high knock values when moving from a standstill, pulls and normal driving/cruising is fine. HELP!
I just got my cobb AP a few days ago. Still stock tune though, I wanted to monitor my car for a little while to get a feel of how it works.
Did some searching and I found that Wiseco 1400HD pistons seem very tough as far as pistons go, and didn't carry a ridiculous price tag.
My question is, being that I don't know jack about internals, is it okay to put forged pistons on 4B11 that I have no intention of ever putting a...
I've tuned a few 2011 GSRs recently...it it just me, or do they seem more sensitive to knock than other years? Mind you, I don't hear audible knock, but I get a few knock counts even on a stock tune on a stock car. Is it just me?
First time logger here with my Cobb AP. Don't know much about this so help would be greatly appreciated.
Mods are Exedy Stage 1 clutch, Cobb Stage 1, Cobb intake, APT UICP. Did some research on what to log so let me know if I should add/subtract parameters. No AFR gauge. Temp was 79* and...
