Hey everyone I have a small question about some RPM behavior on 4rd gear WOT pull. There is a small spike on the line that I can feel while WOT-ing (This feels like a 2 waves of ppower instead of one): This started today but I can't see anything strange inside the logs. I added a full log with...

Hello pals I am sure some of you are not only car enthusiasts but computer genius too. A long time ago I found on this website this awesome file that was used to make almost any work on our car. This was the link for downloading the program...

Hello everyone After making some upgrades I am trying to understand why the temperatures I have got arent the temperatures I was expecting to get. Short explanation: 1. Before I touched the system the delta between the ambient temperature and post intercooler temperature was 8-7C. It wasn't...

Hello pals Last few weeks I have spent a huge amount of time driving around and trying to find the best MAF values to fix my AFR on WOT and LTFT. I have got good results with the MAF adjusting: - LTFT changed from constant -11 = -6 to -3 = +1. - AFR before: minimum 8.3+- at the moment the boost...

Hello pals I want to adjust my MAF section to get a better AFR rating (goes as rich as 8.3-9.8 on WOT while the target is 11.2) and normal LTFT in summer is 9-7%. I used this video to understand the concept: Now, I understand how he does it, but I don't understand the formula In his excel...

Hello pals Cut the long story short - there is a button (Arrow) in Ktuner software that allows me to download the base code. It is always grey(Non-clickable). What do I need to do to make it work (Clickable)? Do I need to flash my car back to stock for that? Thanks for the answers Best regards...

Hello pals Cut the long story short - why I see a few lines in this window? on Ktuner website, there is only 1 line under each option (Post start, Normal) and it makes sense while in my software I can see a few lines under each option(target target target).

Hello pals Last few days I was looking for a few tables on Ktuner that I never touched before. I found that on NonBeta version I have access to "Knock sensitivity Cylinder X-X". The same tables are disappearing when I switch to BETA version. Why this happens and how I can access these tables...

Hello pals After tons of research, I decided to buy the 27won FMIC. Something in their development blog just made me fall in love with the way they do things. Since one of the forum members already made a great performance review...

Hello pals I am looking for a sound clips of FK7 with only DP/FP cattles combo installed - no exhaust, deleted parts etc. Just the DP/FP combo with stock exhaust. Want to understand if the cattles will be bearable for a daily or I should go catted (prefer cattless but have concerns about the...

Hello everyone I considering to buy 27won intake. I like the design and the fact that the filter itself is accessible from the hood and no need to take the bumper off. Was thinking about PRL cobra but left this idea. My only questions is the filter itself. 27won uses DryFlow K&N/AEM filter. I...

Hello pals From the moment I bought the Ktuner unit there is one thing that always makes me confused. Maybe someone here will be able to make it simple for me. When I first plugged in my Ktuner to the car I got 2 sets of tunes: - Normal version of Ktuner package (St1, St2, Starter 21/18/16.5...

Hello pals Unfortunately, some stupid children threw a stone on my windshield and it got cracked. I am looking for Honda files for how to make the replacement before I am going to the dealer (I have the Honda sensing, So I have a lot of things to worry about with this replacement). I have the...

Hello pals Last weekend I were cleaning my stock calipers from all the dust and dirt that stuck there (started to squeeze). My model (FK7 manual) has the Ate calipers from the factory with 2 sliding pins. When I opened these pins they felt like almost unscrewed, a very small pressure needed to...

Hello everyone PRL and RV6 offer 300cell. 27won offer 200cell (and this is what I am after for now). Simple logic says that if we take the same amount of unburnt fuel (or even more) and throw it on a shorter cat with fewer cells - it will kill it much faster. But simple logic fails lots of...

Hello everyone My car is a Hatchback FK7 sport model with manual transmission. In a few days, I will order an Intercooler and already has the Ktuner V2 with 21PSI tune. The next thing on my list is a DP/FP combo but I struggle to decide about the diameter and thus cant decide witch company to...

Hello CivicX community I want to ask please from experienced tuners here what can be the impact of the "Early spool" on a fully stock car. Does it have some negative effects in the long run? From reading the forum, few PDF`s and Ktuner website I think that I understand what "Turbo spool" and...

Hello CivicX community I decided to make a thread about an official normal values for K.count/misfire and fuel trims that I found in Honda service books for our model. Take this info as an answer for when you really need to worry and when its just something you need to keep your eye on. Hope it...

Hello CivicX community After choosing an intercooler I want to order, I started to look for a downpipe. Unfortunately, its hard to find articles about the impact that downpipe has on other exhaust system parts. Can you please explain it from your personal expiarence/knowledge? Basically what I...
