I am having an issue with my adrenaline. Saturday I went to dyno the truck and I wasn't getting as much fuel above 2000 rpms as I should have. I think there is an issue in the box with the map sensor part. When the adrenaline harness is plugged into the map sensor the voltage is 0.983 and on the drb III it reads 13.5 psi. When I unplug the adrenaline and hook up the truck so that it is back to stock then it reads 1.05 volts and 14.5 psi. Could anyone else tell me what the voltage readings are for their map sensors. If you don't have a Chrysler drb III handy then all you have to do is to look for the dark blue wire on the adrenaline harness and take a volt meter to it while grounding the other side of the meter. Then plug it back to stock and the wire won't be dark blue but i believe it is the bottom one on the connector, check it and see what voltage you get there. If anyone could do this for me I would greatly appreciate it! I really don't want to send my module back if I don't have to.

 

Can anyone help me out. I really need to get this fixed soon.

 

Try to upload a different tune , as they seem to expire after so long

 

I have the 2000 tune in it now and I just downloaded it. I am going to try the comp tune tonight. I just told it to run from the internet instead of saving it. The readings that I had were with the adrenaline set to the 0 level so I wouldn't think that it would matter what tune was in it.

 

Re tune it and report back

 

I loaded the comp tune and also updated the pulse. When I did it I just ran the programs straight off of the net and didn't save them to my hard drive. The map sensor volts are still off from stock but the truck seems to be getting fuel now. I didn't get a chance to drive it but I should get to tomorrow and will report back how it is and if it says running good. Thanks DieselMinded for the suggestion.

 

My map sensor reads 2-3 lbs less then my boost guage!
Always has! As for the voltage I can't help! But it also tells me my fuel temp Is 112 when its 60 outside and been parked for 24 hours, and 215 atv its hottest!

I try to document these things, for my sanity!

 

Just popped in my head!

Have checked the wiretap on the vp? Make sure clean and making a good connection!
I was just looking @ mine when I got the idea, I had to tighten mine once! I used a potting compound to make sure it doesn't cone loose again.

 

215?!!!!! dang, the hottest ive ever seen mine after running a 4 hr trip was 160 degrees with 16 psi at WOT

also, my map sensor reads 2-3 psi lower then my mechanical boost guage too!!

 

Thanks guys I finally figured it out. It was the bd stealth cover. Everytime I got the truck to the garage to check it everything was ok so I took my test light with me and when I was on the road and it did it I checked the wire and sure enough there wasn't any juice in it. Screwed the needle in a little farther and all is good!
