Went and met up with JaiKai for the first time today and got the Zed plugged up to Conzult (top guy, had a good look at his Zed's and got some ideas :p ).

 

I will post up the screenshots later once Lee emails them too me but I have a question in the mean time, is 30 degrees BTDC a bit excessive for the timing?

 

 

Reason I'm asking is I still have problems starting from cold and this could be the cause if it's far out, according to Jeff when I first joined the forums.

 

Any help would be appreciated guys!

15 degrees btdc is what it should be iirc

Correct!!

Look forward to seeing the screen shots, meanwhile the 30 deg, is that what the ConZult read at normal operating temp? if so that means you have issues elsewhere such as temp sensor or tps hard idle switch.

 

The 30 deg reading is not necessarily what the actual timing setting is, just a calculation within the ecu based on what it is been told from the live sensors readings etc. so basically its a wrong reading cause by an issue elsewhere that we will see soon eh?

Right - Sorry for the delay on getting these up

 

Not an excuse but been watchin xfactor with the wife!

 

 

 

Mark had some issues with starting from cold too and seems that

when starting from cold the car is getting too much fuel so heres

a few more shots of mapping currently setup on his zed.

 

 

 

 

 

 

Thanks for that Lee! Been forced to watch this X-factor carry on as well -.-

Ok the lack of closed throttle hard idle switch is the reason the calculated ignition timing is so high at 31 deg btdc the waste gate solenoids and variable valve solenoids are showing active for the same reason, the injector pulse is also high for tick over but again the hard idle switch issue really means the information is flawed and needs doing again after the issue is resolved.

 

Any starting issues could be attributed to the poor set up.

 

The ecu looks to be fitted with a JWT chip or at least a clone of.

Thanks for the input Jeff where do you think I should go from here as im slightly confused lol. I originally thought it had a chipped ECU but I changed it over for another ECU from my breaker thinking it was standard :/

The ecu or at least the chip is definately not standard, good for boost upgrade and more power yum yum.

 

The throttle issue needs sorting and then the ConZult doing again.

 

Jeff TT

I'm lost as how to go about sorting the throttle :/ Need to get a hold of a standard ECU as well and keep the JWT one for when im feeling the need for power lol. Also my o2 sensors are away... long story short how much would I be looking at roughly for all this rectified at Zedworld with you Jeff.

I'll just have to treck it down the 260 miles with her :)

> I'm lost as how to go about sorting the throttle :/

 

disconnect the tps connector (the one on a seperate wire) for 5-10 seconds while the engine is running.

It will reset the idle switch setting in the ECU

Thanks Lymon was out at it this morning and reset it and brought the idle back down to normal. It seems to have a bit of a flat spot at the bottom end now so I've decided I've had enough trying on my own lol.

 

Gonna try sort out time off from work before xmas or worst case after xmas and get down to Jeff if I can get it in! I'll give you a PM Jeff (y)
