Default LC1 woes

New problem:

On my drive home today I got E2 followed by E8. I turned the car off, wondering if it was just a sensor overheat (a problem I have not had since installing the heat sink). After a short while, I started home again, staying out of boost. I got wb readings for a minute, then E2 then E8. Repeated a cool down. Got a drink for myself, started home again, staying in light load/high vac. My xd showed E8, then it HCL (heater calibration). It did the heater cal, then it did a o2 cal. And now all I get is E8.

Ideas?

The sensor is in a new DP, but is roughly the same distance from the turbo as it was before (it's right before the flex pipe)...

Did a complete sensor calibration and it's up and working again. I also regrounded the heater ground for grins and giggles. Biggest shocker was the LC case was starting to distort a bit from the heat. In fact, it warped a bit making it tough to pull the sensor harness out of the LC. I plan to wrap the LC case with heat wrap, but didn't have time then, so I just folded one of those silver heat blankets around it. Good enough for now.

Jerry @ DIYAutotune went well above and beyond trying to help me with this, I didn't even purchase my LC1 from him! Guys, if you're getting an LC1, I recommend you give DIYAutotune consideration. Their tech support (Jerry) was better than the support I've received from Philipe at Innovate.

Where is yours mounted? I've got mine on the ppf and haven't seen any evidence of damage from anything. Bad grounds have given me grief before- like inaccuracies in gauges.

I had to be a rebel and put mine on the brake booster. The ground looked fine, I stripped the wire back and re wrapped it to the bolt just to do it.

I'm wondering if the problems were caused because the LC unit itself was over heating? I had the tony pipe on (boost was 15 psi spike dropping to 10 ) and no heat shield over the turbo. And it was basically right next to the downpipe.

On that note, I did NOT adjust my MBC. Before with greddy pipe, cat, and muffler I was holding 8 psi pretty steady. After with tony pipe open to atmosphere, 15 psi drops to 10 psi. I couldn't fuel it correctly though, even with the MBC at its lowest setting, so I'm back to WG for now. Hopefully Jerry @ DIY will be helping me out with this though.

I ordered my LC-1 tuesday morning from DIY and it came in today. 2 days delivery time was great. I went with DIY even though I could have gotten it locally for the same price or off ebay for 20$ less because I love what they are doing and know they will support the product if I have any questions. Hopefully tommorow the isntall will go fine.

I have mine installed in the cabin. Routed the harness sensor up through the trans tunnel. Easy to wire this way and out of the elements.

Tony's downpipe is the cats ***, really woke up the greddy!
