Did your under drive pulley already have the timing mark, or did you put it in there?

yes m8 there unortherdox pulleys but as you can see the Sprocket the belt/timing slot/dots all align up ..

put the pulley on and that aligns up with 0*

Did you have a look at your IACV on the back of the plenum? Did any crap get in there whilst rebuilding or it may be dirty from before?

changed it for another one ... the Full unit

Yeah bloody Fixed it .........

 

 

 

its the Map on the ECU Chip ...

think JD's chip isnt right on something injector timing/pulse ... not sure but i have a Back up one from AndyP ...

 

popped it in and hay presto all ticks over fine and no flat spots I'm Well happy :)

Nice work. Could it be the wrong spark plug gap for the chip?

Well done bud, I bet you are well chuffed!!

Well done mark, if anyone was going to solve it, had to be you! lol.

 

Well pleased for you mate.

happy you fixed it mark, you seem to be able to sort any issue out! :bow:

 

so whats wrong with mine :whistling:

ok think i spoke a little to soon ....

 

Tick over and rough running has gone but i get a

stutter/miss fire around 4k

i'm going to swap out my old plugs thats in there used for testing and refit my ngk7 ..

tomorrow see what happens

 

only boosting at 11psi ( stock ) but with this cheap the AFR on boost is sitting at 10>11 ...

think this is way to Rich .. as with JD chip is was more like 12>13

 

it only happends if u put your foot down hard .. other wise u do it nicely its fine

Sorted ... bloody Maf Plug not connecting propers .. Doh!

Lol, so is this working alright with the JD chip now?

no still the same with JD Chip ...

I thought the TPS was supposed to be set at 0.50......guess I'll be resetting mine to 0.44 then!
