zanzabar Posted December 19, 2013 Share Posted December 19, 2013 i picked up an obd2 bluetooth that was recommended on nasioc and was playing with it. what i came across was that the throttle sensor never reads higher than 79. it seems accurate at what other possessions should be but it only reads 79 with my foot on the floor. i was also looking at the boost only hitting around 12lbs, i was a bit confused since it should be reading MAF and not a MAP of actual boost so the stock tune with 13psi (or 14psi i was not sure) should get that reading or close right? | TLDR, is having torq and a bluetooth OBD2 reader seeing only 79 on throttle percent when floored a problem?

Max Capacity Posted December 19, 2013 Share Posted December 19, 2013 I guess its a case of don't believe everything you read. My wagon was tuned on a true reading Mustang Dyno, it feels a faster then the numbers. If you want more power, may be put that money towards performance parts instead of a toy. You also have a 5eat, they can take more power then a 5mt. 305,600miles 5/2012 ej257 short block, 8/2011 installed VF52 turbo, @20.8psi, 280whp, 300ftlbs. (SOLD). CHECK your oil, these cars use it.

xt2005bonbon Posted December 19, 2013 Share Posted December 19, 2013 I've been using the torque app for 2.5 years. It's been working great for me apart from having a slow refresh rate (probably due to the bluetooth dongle, not the app itself). As for accuracy, I'd say it should be accurate. For instance, when I was stock I recall seeing my peak boost around 13.5 psi consistently. Now that I am stage 1, my tuner set my tune to reach a max boost of 16.9 psi. Last night, the torque app registered a max boost of 16.6 psi, and the day before 16.8 I think. So it should be accurate. Link to comment Share on other sites More sharing options...

There are cables available that connect the OBD port to the USB port of your phone, and provide higher bandwidth than the bluetooth dongle. I haven't used them - I only have the dongle, because I only used it for reading CELs on my old 2.5rs and on my miata. I have an AP v2 for my LGT, so I don't use the torque app in that car. Although, since I have both, I could do some comparison testing one day. Link to comment Share on other sites More sharing options...

I was told not enough flow for that boost. Link to comment Share on other sites More sharing options...

It's been working so far. You could send the question to my tuner. He'd be happy to explain. He is good. Here is his vendor specific forum and his website.

DonnyJagaru Posted December 19, 2013 Share Posted December 19, 2013 There's a setting in Torq to up the communications speed to the car. Some cars don't like the higher speed though. I would guess the application is as accurate as the data feeding it. This is all standardized open source stuff, no? I am gonna check my TPS now that you've mentioned this though.

zanzabar Posted December 20, 2013 Author Share Posted December 20, 2013 with the car running or just the ignition on but not running it tops out at 79. i think i am going to call the dealer that did my AVCS problem and see if they will check it for me with the dealer reader. the car accelerates quite a bit different since i had the AVCS fixed so i wounder if they changed it to lower max throttle while fixing the problem.

DonnyJagaru Posted December 20, 2013 Share Posted December 20, 2013 I just checked my TPS on Torq and it maxes out at 79.2%. There are two other Accelerator Position options D and E, but these are similar. If you slowly press the gas pedal down the display jumps from 17% at "idle" upwards. Its definitely not a linear progression so I'm not convinced its accurate at all. Whether or not it should be reading 100% I'm not sure, but my previous car definitely did. Let us know what you find out. Link to comment Share on other sites More sharing options...

xt2005bonbon Posted December 21, 2013 Share Posted December 21, 2013 good to know. will that work with a cheap blue OBD2 reader? I don't think it will. I use a VAG COM cable and a laptop running windows. I use romraider when I need to log to improve/adjust my tune. Link to comment Share on other sites More sharing options...
zanzabar Posted December 23, 2013 Author Share Posted December 23, 2013 today was warmer 60f, and it is running 13.6lbs of boost all day when it pulls. i also think that i am just going to ignore the throttle since it seems like the app is not accurate and i am getting the turbo swap and tune in the spring.

DonnyJagaru Posted December 23, 2013 Share Posted December 23, 2013 I'm wondering if the TPS is on the slave servo and the car computer is not allowing more than a 79% opening during idle or engine off conditions. Just thinking out loud here. I guess I could run the app and go floor the accelerator. Link to comment Share on other sites More sharing options...
zanzabar Posted December 24, 2013 Author Share Posted December 24, 2013 it says 79 in every gear. i have even reved it out. the boost is where is should be (or where the computer should think it should be) so i think it is just the app. Link to comment Share on other sites More sharing options...
