I'm sure they do have a MAP for the 300, because Graham has a 300 EJK unit but to be sure email Matt mstoxen@dobeckperformance.com. He is a very helpful guy.

 

Hi guys, I am back online after a tripping around our planet. There is no map for a 300. The 250 Juicebox/EJK/Wisceco/ are all manufactured by Dobeck and in standard 250 format deliver a trickle more fuel than stock. THIS WILL NOT WORK ON 300 PLUS cc. The reprogrammed unit delivers WAY more gas and floods the 300 on the upper settings. This in my opinion will work on the 331 kit that I am about to install, However anything higher than 331 and the fuel requirements may max out the injectors. I know of no 350 using EFI.

 

So it works ok on the 300 unless you use the 6/7/8 settings?
On yellow,green and red mode?

 

The reprogrammed unit works perfectly on my 300. I play around with the lower settings in all modes.
The upper settings deliver too much for my 300, so I believe it will work fine on the 331 as well.

 

Question is this api adjustable? because it has *****

also can someone translate ha! no english manual for api pffff

 

have you emailed them?

 

i sent you a PM

 

Yes gazillion times

What happened rinoabilog? Did you ever get it running properly?

 

OK, the reprogrammed EJK works on the 331 EFI, still with room to increase gas flow on the units dials.
I popped in a KK 331, plus Webcam 101 grind Cams and the little beast is pulling like a train. Maybe the injectors will handle 351 ?, maybe? any guinea pigs? Any guys gone over 331 yet on EFI?
Please dont make me another piggy.
