I'm not sure if this is the place to post this but I'd figure it's where I'll start. I just did data logs on both my unleashed 93 tune and my AJPTurbo tune. Both Torrie and Brad said that the charge temps were really high ~170 degrees. Any ideas on what's causing it or how to remedy it?
Also it's throwing a P0035 code - turbocharger bypass valve A control circuit high. Not really sure why that is or how to fix it.
My current mods are ngk plugs, 170 degree thermostat, 3bar map, MDesign intake, EPPcharge pipes with tial bov, Livernois catted downpipes, borla catback. On a '14 ex sport.
Any and all help is greatly appreciated.
I remember reading somewhere that the bypass valve or wastegate was stuck shut (or electronically not opening) and causing heat to build up. I believe they had debris making it stick but have also heard it being a sensor that failed.
Have you had any power issues lately?
What I found...
Symptoms
Symptoms of a P0035 engine code may include:
*Increased engine and/or transmission temperatures
*Random noises from the turbocharger wastegate and/or hoses
*Reduced engine performance
*Black smoke from the exhaust system
*Other turbocharger boost related codes, engine misfire codes, or knock sensor codes may also be stored
*The spark plugs may be fouled
*Hotter engine temperatures may also lead to cylinder detonation
Causes
Potential causes for this P0035 code include:
*A defective boost pressure sensor is possibly the most common cause of a stored turbocharger bypass valve control circuit high code
*Turbocharger bypass valve failure
*Collapsed, disconnected, or split vacuum lines (applicable for vacuum actuated bypass valves)
*Turbocharger bypass valve actuator problems
*A shorted or open circuit in the turbocharger bypass control sensor circuit
*Loose, corroded, or disconnected electrical wiring/connectors in the turbocharger bypass control/boost pressure sensor reference circuit
*A bad PCM or boost controller
The IAT Temps should not exceed 150 deg IIRC! What exactly did you use for vacuum reference for Tial BOV!
Did you leave the Front BOV unplugged and Rear BOV plugged in !!! Z

I'd say the high IAT's are simply the Mdesign some way or another sucking in hot engine air. There has been quite a few of those that had snorkels that were warped and or cracked.
I emailed you but your 1st tune did not have the changes for the aftermarket BOV. Your 2nd tune should remedy that.
Thanks for the help so far. I know the bovs are both unplugged. Guess I may have to take it back to the dealer to see. I have a 3rd party extended warranty so the dealer has been super good about fixing stuff despite the mods.

You may not have anything wrong. Are you running rev. 2? Normally if your tune does not shut off the BOV control you need to leave the connectors plugged in to the stock BOV's and leave them in the engine. But if your tune does shut off the BOV control you can normally leave them unplugged and take them out. But I can also see a scenario where the ECU doesn't like them being uplugged at all.
If you have an aftermarket BOV and you are getting cel's for BOV codes and you have unplugged connectors you are probably wasting their time.

It's been a while, but I did not have any codes or issues with your tune(s) for the TiAL and the stock stuff sitting in the trunk disconnected

I just flashed rev2. No cel yet but I haven't driven a ton. The iat2 gauge on the bdx never got over 140 degrees while I drove it around though.
