syclone #1322
my syclone is missing at moving speeds, when in idle seems to run alright, but when cruising at any speed 40, 60, 70, seem to have a miss, could it be my fuel pump going out or just a sensor, in the weekend it died on me twice but it would start right off, i have 82.000 miles on it know and never replace the fuel pump, another question i had is it possible for the syclone to go over 10lbs of boost without over boosting, i got the water/meth setup and works great, got it shooting at 10lbs, runs great at 10lbs of boost, but when i go to try to get to 15lbs it starts bogging down, or over boosting, does the 2 bar map sensor have something to do with that, or do i have to go with a 3 bar map sensor, i know i have to use datamaster to see whats going on but if there is anybody that have a cable for sale i would love to buy it, got the laptop and software but no cable, thanks if anybody can help really do appreciate any help i could get!!!!

Sounds like you have allot of stuff going on with that truck.. do you have a scanning tool ie datamaster, tunerpro rt etc?

If not you should or at least reach out to the syty owners that are local to you that do have one so you can find out what exactly is going on with the truck.

Sounds like to me you have a few different issues.. when was the last time you did a plug/plug wire, cap/rotor and fuel pressure change?

Do you have a fuel pressure gauge? what psi are you getting under boost?

Stock boost for these trucks is 14.5 (2bar map) anything over that with the stock chip will cause an overboost.. so over boosting at 10 psi isn't the issue. Something else is wrong.. and you mention when your meth injection kicks in at 10 psi the truck bogs?? that sounds like either your spraying way too much meth (adjust it) or your plug gap is wrong. Do a search on here on plug gapping with alky injection.. most run something like 26 or 28 where is stock would be 34 I think.. but again do some searching and reading

Also you can't just throw a 3 bar map inplace of the stock 2 bar map without getting a chip that's made for the 3 bar.

datamaster cables I believe are sold by eric at www.turbotime.us and www.moates.net
right now I don't think there's anymore members producing the cables

Re: syclone missing

well the first thing i want to do is get a cable to use datamaster, and see what is going on, the second the plugs are new and pre-gaped and have not been gaped, i know for a fact there are not at 25 cause i installed the plugs my self, got to check the fuel pressure to, but like i said it still missing at any high speed, but whats weird today i was coming home and no miss and parked and waited for my boy and started it up and started missing again, freaking weird, but i need datamaster to look at everything, and thank you for you help love this forum, and appreciate all the help from you guys. :tup:
