If you don't have OEM V-clamps, that might be the problem.Going over to a local shop right now, they charge 89$ for a diagonistic lets see whats causing this strange codeĭTC stands for DIAGNOSTIC Trouble Code. I would encourage you to loosen up the mid-pipe connection and then rework the v-clamp. V-clamps can be a bitch to work with, and somewhat deceptive. I've been hearing stuff about MHD 10.0 maps in beta right now, hopefully soon it'll be released for the public to use Yeah, MHD 9.0 is so much smoother and refined compared to 8.0, I'm hitting 19+ boost as well, feels amazing I have Index 12 Injectors, when I did do a smoke test though I did notice smoke coming out of the connection between the downpipe and turbo where my v-band clamp is, which is why I suspect it's the clamp since I replaced that paper gasket that sits between the downpipe and turbo. If replacing the O2 sensors didn't work, my impression is, from what I have read, the next step is to do a leak down test & or replace the injectors. I think putting in new O2 sensors may have done the trick. The is actually dip into the 12's when you accelerate onto the hwy. ![]() They fluctuate between high 13's and 15 on the hwy at 80mph. I just checked my lamda 1 & 2 AFR's in real time on a drive, and they both seemed to be with in spec. I think they are better than the regular OEM seals myself. I used burger motorsports mid-pipe seals. So, the seals at the mid-pipe & turbos are brand new. I just put in new RB OEM + turbos back in January. however, I came to find out I have a damn exhaust leak between the turbo and downpipe, I changed the gasket and that didn't fix it so I'm assuming it's the V-Band clamp, also under boost I hear like a "wsh wsh" sound.Ĭould it be you're dealing with the same issue? Coincidentally this started happening when I went catless and I put brand new O2 sensors as well. I've been dealing with this same problem except for both banks 1 and 2 (two codes), running the same thing MHD 2+ V9.0. If this doesn't work, I guess I will be taking advantage of my lifetime warranty on the index 12 injectors that probably don't have 40,000 miles on them □ I will be replacing both pre-cat O2 sensors this weekend. ![]() In other words, both codes combined likely indicate a tuning issue." It’s unlikely you have a hardware problem on bank 1 and bank 2. If you’re getting this code along with 29E1 (fuel mixture control 2) then you’ve got AFR issues on both banks. Fuel injectors are another common problem that triggers this code. Faulty O2 sensors may trigger fuel mixture control 1 codes. Fault code 29E0 can be a tuning related or hardware issue. Not experienced this problem but are you getting the same code on v7 as well?įuel mixture control 1 indicates you are having air/fuel (AFR) mix issues on bank 1 (cylinders 1-3). Anyone have any experience with this one?
