Every once in awhile at idle ill get a small surge, and itll go away, but today the car as pulling out into first bogged down and sputtered like crazy, couldnt even press the gas to move, just surging. so pulled over and turned it off let it sit, cranks back up normal. just the rpd reads no data for the boost. im thinking either the sensor is going bad or the hpt gms1 tune has a bad file possibly? The connections for the sensors are soldered in and heat shrinked wrapped, with wire loom also.The bottom sensor does have the small piece shaved off also. And no cel's were thrown.


Inputs?

 

Warranty

 

did your whip come with the RPD or not? -if it did. bring it in for warranty, if not, warranty isnt going to cover it..

self-installed mind and had a problem with the screen, got warranty on the screen..

 

came with rpd, now its reading fine, sensor might be going bad, since i got them from someone off the forum here with the gms1... ill be checking them tomorrow.

 

If you're pushing 24 psi, it won't read that.

 

really that sucks ... the gauge itself goes up to 30 psi ? does it just no go beyond 24 ?

 

Mine reads out to 25.5 on the stock sensors before it blanks out..

 

This will go away and come back. It is related with readings above 24 PSI. I've seen mine read up to 28 PSI and be fine. I wasn't fine though because I shouldn't have been boosting that high.

Other reason it would do this is sensor related.

 

its only on 20-21 psi spiking 24 sometimes... and i wasnt even boosting when the car was surging, and when it wouldnt read boost.

 

 

If you go over 25 psi for too long you blow the map sensor. Same **** happened to me. You're still on the stock map sensor and not the 3 bar, right? Having a bit of a rough idle?

 

^Im sorry but that is not true at all. I ran 30psi for 10K miles and I still have the same sensors in my car right now.

 

it has 3 bar map sensors, and hpt gms1, but now i have another problem, the car wont start

 

Hmm, nevermind, then. I have no idea what caused mine to go, then. Haha.

 

mine was the map sensor

 

Check your intake and MAF sensor making sure everything is connected properly.

 

Every once in awhile people seem to have a failing MAP sensor issue. Ive seen 2 people that I tuned keep blowing them even at 22psi. There was some issue with a lot of sensors.

 

CAR is stock besides the hpt gms1 tune, i had already checked that though, with all piping to see if anything popped off. but everything is alright. maybe a file is corrupted somehow.

 

samesos! Never blew any map sensors. Some cars eat them, some don't

 

I got that message on my RPD a few weeks ago. MAP sensor (the one on the intake manifold) took a dump, replaced it and all is happy again.

 

yeah i figured that part out, but, now the car doesnt even start. after that happened. tried the stock ecu , and the hpt ecu, neither one starts the car/

 

You broke it. lol

 

lol byt

 

I think this just happened to me on the way home. I kick it with my trifecta tune on and it gives me the no boost sign. I slow down i switch tunes for a minute to make sure everything is ok...i switch back to trifecta and its reading boost again. everything is good for now...is this what everyone is talking about? how much are these sensors, how many are there, and are they easy to replace or should i take it to chevy? Ive got warranty but its not too crazy of an issue yet sense it just happened but if its an easy fix ill just keep the car out of the shop.

 

go on ced sensors are 15 bucks plus shipping, if you have the 3bar, stock dont knpw how much.
