This is a continuance of a question I have for Mike @ Innovative but I thought I’d put it out there so others could benefit. My Z has run rich since day one and the tailpipe smoke is let’s say…excessive. I know Mike checked it out when we did the dyno pulls and said it looked fine but when I posted on another site some time ago, a concern called “cylinder washing” was brought up. I also considered that if I’m getting soot building up on my exhaust tips, would it stand to reason that it’s building up in other more important areas? I know rich is safer than lean but could it also be detrimental? Anyone with personal experience / suggestions / advice (especially Mike) would be appreciated. Just obsessing and putting it out there. ---

I’ve pretty much have come to the conclusion that whenever someone speaks of “cylinder washing” they have no clue what there talking about. Cylinder washing is something that doesn’t happen on modern day efi systems. Unless your replacing spark plugs every five minutes (literally) to keep your car running then you have nothing to worry about. Sound to me more likw you have oil burn issues in which case id start checking turbo, pcv, leak down, etc to find out the smokey culprit. ---

Sounds like it’s running rich. What do you have to tune the car with? What mods are done on the car? ---

Nothing on that list says what tune / program you’re running. If you don’t know, take a look at the ECU (this link will tell you how to get to it: [http://www.ttzd.com/tech/diagnostictech.html](http://www.ttzd.com/tech/diagnostictech.html)) and read what it says on the top of the box. If their isn’t a sticker there, then carefully pop the top off and read what’s written on the EPROM chip. ---

You can get fuel wash happen with modern efi. It happened to me last spring. My rings got fried and never seated due to being way to rich. Even after cleaning up the tune it didn’t matter since the rings were fried so I had to put new ones in this winter. Do not keep driving the car until you get a wideband on it. Check your oil. If it is super black like diesel oil and has a gas smell to it your rings might already be fucked. ---

If it is super black like diesel oil and has a gas smell to it your rings might already be fucked. This would be much easier to accomplish on unseated brand new rings. However this is not an easy thing to have happen. I have had an injector stick open and load a cyl with so much gas we had to pull the plug and literally let a waterfall of gas come out to not hydrolock and bend rods. There was not “cylinder wash” I am with John(turbociv) on this one. Also 1quick if there is one thing I can not stress enough it is that you should always hold much MUCHHHHH more weight on something that a professional(Mike@Innovative) has told you over some guy on the internet that is simply regurgitating some term he heard used by someone once before. ---

I do hold Mike’s experience in high regard, but I also like to have others opinions, just like with doctors. As I mentioned in .the earlier post I am more concerned about buildup in sensitive areas (turbo’s, valves, etc.) I just wanted some other viewpoints, and wanting to know if anyone thinks I should be overly concerned. ---

That is my point, you would seek another opinion from another doctor. Not a guy on the internet. I am not giving you a hard time at all and added input is always a good thing I was just speaking from experience there. Do you have a video by chance of the amount of smoke? A turbo car is going to be tuned pretty rich generally as rich as 11:1 isn’t uncommon and this will produce some smoke. ---

If Specialty Z owned the car then I’d imagine the ECU was chipped / tuned. Or they could have just installed a “close enough” map like I have. But looking at your dyno sheet makes me think something else is up (I only glanced at it before.) 388 hp / 361 tq is REALLY low for the mods you have. For reference, I made 300 hp / 320 tq totally stock with the exception of 1 JWT pop charger and my Weisco pistons. Leaking shitty stock turbos too. Do you know how much boost you’re running? What boost controller do you have? When you check the ECU using the link I posted above, also do the ECU diagnosis and let us know if there are any codes. ---

Your 300 hp rating is stock at flywheel and I assume that’s based on factory dyno tests / numbers. I ran on the Mustang dyno @ Innovative and that’s supposed to put out more “real world” numbers. Specialty Z’s dyno spit out 460 at the rears. I know running rich is going to rob some power but I told Mike I’d rather be safe than sorry but I also want to make sure it’s not running obscenely rich. Will see if I can look for more info. on the ECU programming. Blitz boost controller, Apexi AF controller.
