SLP resonator delete issue.......

[MudnRox]

I'm getting "soot" build up on the paint behind the tips. Even using the foaming brush at the car wash won't take this stuff off. Only way I have found is to use Simple Green sprayed in a rag and wipe it off. There is no sign of any heat damage just the soot. I really like the resonator delete and don't want to take it off but I'm not sure of any other ways to solve this issue. As it sits now the tip sticks out past the body about 1 1/2 inches. Maybe have a muffler shop run it out to the back instead of the side. But I'm not sure how that's going to look.

Anyone else have this problem and what did you do to solve it.

It's not the best pic but you can get the idea.

I would guess the issue isn't the tip itself. Rerouting it would just result in soot on the rear. I'm not sure what's causing the soot.

I see some data logging in the very near future.

Yeah, I've had the delete on mine since last summer and the tips get dirty pretty easy but I haven't had this. Seems odd that it would run rich enough to soot the paint but not throw a code. My 99 threw a lean code at +/- 20% fuel adjustment, not sure about the nnbs programming conditions but, it can't be that different.

That's why I didn't really even consider the possibility of "running rich". I thought if it was that rich there would be a CEL. My mileage is off about 1 mpg. I figured it was due to winter fuel.

deleted mine a few years back, no soot...sorry.

In KC we have the opportunity to purchase 87 octane without ethanol and 87 octane with E10. You may want to change the fuel you purchase to the other kind and see how it works. I use 87 octane without ethanol and have not noticed any excess film on the bumper. SLP tip on mine too.

I'm out in Olathe and have yet to see a station that has gas without the E10. I run 89 in mine all the time. I've tried 87 in mine several times and for whatever reason it just doesn't seem to like it. That's why my tune is set for 89. I always get gas at Quik Trip, have for years and never had any problems with their gas.

I will do some research around here and see what I can come you with. If I remember right I think Casey's has it bit we don't have any of them close to Olathe.

I'm going to hook up the autocal and see if I can get some codes to pop up. I'm also going to do a data log run and send it in and see they they can see something or work their "black magic voodoo" and rid this thing of the problem.

sbubbaklein you have a really cool rig. I'd love to see it up close some time.

sbubbaklein: Where are you finding 87 pure gas?

I can only get 91 pure gas at HyVee. But I found in an experiment last summer that the increase in mpg more than offset the increase in price. But would like to pay less for 87 pure gas. ☺

 

[NGAneer]

There's pure 87 at about 1 out of every 10 stations in Northwest Georgia. People are clanish as hell and don't trust anything new or unfamiliar.

This, or know of any with pure 89??

 

[sbubbaklein]

I get 87 w/o ethanol at Break Time. It is associated with MFA. Might want to google MFA.
also try pure-gas.org

have been reading that quick trip had some E087pumps. They were red with red hoses and pumped pure 87. Some talk on the internet about 119th Metcalf, may not still exist.

I have this same issue. I'm following this to see if someone had a solution. I wondered if a catch can might help. I have no idea if it will or not, that's just a question.

Break Time is only in Missouri. I don't get over there too often except during the summer going to Smithville Lake

I fill up at Quiktrip. Isn't that 87 pure gas or am I mistaken? I use 87 in my truck and 91 in my burb.

Went out to do the data logging drive. When I got the autocal set up in the car I got a 0280 code that popped up on the autocal. Not sure what that is. Whatever it is it wasn't enough to trigger a CEL.

That is an AutoCal code: either you have the wrong configuration, or the key is off.

Key was off for sure. That's comforting to know.

I just emailed the engine file in to you.
