    If you have hondata read the code first and see what it is, most likely you missed a check box on the tune. People lose there shit immediately when the check engine/emissions shit comes on and are like zomg wiring harness. Literally any check engine light will trigger the emissions/rev match disable.

    Man hope you are right, but I’m pretty sure I double checked everything when I’ve reconnected it, but when I get back to my house tom night I’ll reconnect my laptop and make sure

    Had the Hondata tune on my CTR. The 2 warning lights came on after some pretty heavy rain and foolishly allowing my gas tank to approach dead empty around that time. Filled the tank and the warnings disappeared after a day or so.

    Add me to the Emissions problem/rev match fault club. Like djhartm,I assumed I could drive this car from the dealership (where I bought it 2 weeks ago), to the race track. I did that with my Evo and my M3 without issues. Fortunately, I read various posts here (after the purchase) about all the track issues. So I had at least upgraded my tires to Bridgestone RE71R's 265/35/18's and a cheap but presentable set of track wheels. Cost $200 each vs the stock wheels that cost $1,325 each. Brake pads were ordered Hawk makes a set of track pads for the Type-R, (available from Tire Rack where I got my wheel/tire package), ditto brake fluid but didn't get them installed.

    I ran at Mid Ohio yesterday in the advanced group, with the heater blasting to assist with cooling, in R+ and VSA partially off. The car ran strong (130 mph on the back straight) and kept up with or passed 80% of the other cars (its no match for well driven 'Vettes, Camaros, GT3's etc.). But everything else was fair game.

    It got interesting in the third run. My fuel gauge said 3/4 full but after 3 laps I had fuel starvation and the car went into limp mode (what an appropriate term...), as I entered the straight, so at 45 mph I am giving point byes to guys doing 140+ mph. Not fun, and extremely dangerous to all concerned. And I had to limp the 2+ miles back to the pits. I got the fault codes (emissions and rev) and they wouldn't go away. Although the gas gauge said 3/4 full, I put 9 &1/2 gallons in it. When I restarted limp mode was gone but the rev match still didn't work and the fault codes were there. I did all the standard stuff: on/off, drive normally off the tack for an hour, on/off, disconnect the battery, etc. Nothing cleared the codes.

    As it happened there was a person there next to me who had worked on trouble shooting Type-R issues as part of his employment. He assured me the car was safe to drive on the track. So I did and improved my times every session. Finally, after the last session I parked it and put it in Comfort mode and the fault codes cleared:). By the way, my gas gauge said 3/4's full again but it took 7 gallons. So the gas gauge is profoundly unreliable.

    It was a warm/humid (75-82 degrees) day and the temp gauge went up when I was hammering it and would drop to normal after a half lap of taking it easy. After the limp mode episode I didn't want to have that happen again. I never was more than 3 bars from maximum.

    I ran with VSA partially off. I an not sufficiently skilled to do better with no nannies. I ran with it "fully off" and wasn't as fast.

    I had the same threshold braking "yaw" described by djhatm. And 2 times something kicked in that was the opposite of hyper-speed (hyper-braking?) and the car made a noise and decelerated so fast it snapped my neck forward violently-like hitting a wall. My Honda neighbor said the code was written to add boost to the brakes when it sensed imminent disaster. He also said the car's code is written to determine an over-heating issue when the car heats up too quickly, based on typical driving. So it can trigger limp mode if it heats up fast (like at a track day) even when its really not that hot.

    Verdict: for $36K its a lot of car. It more than held its own on the track and was comfortable there and back. It has its well-known quirks and most can be worked around.
