R32 GTR won’t start

Postby Jg530613 » Tue Jun 19, 2018 11:47 am

Hello all,

Completed a single turbo conversion with ID1050Xs on my R32 GTR And was able to get it started 1 month ago by dialing down the prime pulse timing as I had seen recommended on this forum. At that time the rest of the car was not complete but I just wanted to make sure my new setup worked. Since then I added an exhaust system (was open from the turbo), plumbed the intercooler piping, and re-ran vacuum lines (when it started I had a single line from manifold to ecu, now it runs through a vacuum block). Now it will not start, though it has coughed a few times like it is trying to. I tried adjusting prime pulse timing again and have not seen any correlation. Same with how much throttle I have applied. Any thoughts on why it is not starting now?

Hi

Did you enter new Injector size and dead time ? with the right setting it should start with the base maps

Also if your Injector is high amp you must remove the ballast resistor that came factory on RB26

Yeah I changed all those settings and removed the ballast. I pulled my spark plugs out and they were already pretty black so I tried some new ones this evening and still no luck

Can you send us your calibration file to take look at it.

I got back to this after being gone for a few weeks and still no luck. I was able to consistently get the engine to sputter spraying starter fluid in the manifold with fuel pump fuse pulled so I seem to have at least narrowed it down. I have also confirmed I have fuel under pressure getting to the rail. I attempted to calculate actual pulse width signal at the injector by measuring frequency with limited results. Any fresh ideas are appreciated

Post your map here or contact haltech it way faster than waiting someone here to respond

How did you delete the injector ballast? Did you simply unplug it or did you ground the wires out?
