impulse turbo nytro throttle position #s

[Sledneck_1987]

just wondering what the #s should be at rest and at wide-open. mine is 15 at rest and 65 at wide-open. would like to know what other impulse turbo nytros are seeing for throttle position #s

On any Nytro the numbers should be about low to mid teens to mid to high 90's. On the Impulse Nytro if you want to check the numbers be sure to disconnect the Impulse Standalone ECU first then test.

With the Impulse ECU still connected I get 15 low to 65 high..

As stated Motelyone the Impulse ECU needs to be disconnected for the full range.

my impulse nytro is hard starting when hot and won't idle when hot. runs weird under half throttle but awsom over half any ideas ??? thanks

it sounds like there is a vac hose that's off.

Which system do you have? Stand alone ecu?

Start basic and check your fuel pressure & vacuum lines first.

Hard starting can be a few things. Check that your full pressure is not to low, too low and it will make the sled hard to start. Also, turn the key all the way when you start the sled, don't wait for the surge tank pump to stop its cycle. Check to be sure that your Impulse MAP sensor line is running down to the stock MAP sensor and 4 way vacuum line block at the throttle bodies. It should not be plumbed in anywhere else, this spot only. What kit do you have on the sled (race or original, what size turbo)? Once you get it started let us know what your RPM and A/F ratio are after about 45 seconds at idle. Also, do you have any motor work done? If so, what?



Thanks

standard kit with bigger intercooler and 2871 turbo no motor work just head shim. and just run boost gauge no af gauge.

i just changed plugs before it stated to act up. also had intercooler off to get welded bc end tank was cracked where welded to core. soon as you get over half throttle and build boost runs perfect. so thats kinda got me confused. i checked all vacuum lines and their are none disconnected and all are where that where. thanks for the info guys.
