[S2000 trigger scope]

Hi Adam ,

 thanks for your help .I have attached the cal file and a log file could you please have a look at them 

I have tried various offsets but no luck 

Engine seems to have a low cranking speed but we have tried it on a slave battery which cranks at 260 rpm

Thanks for the reply , no luck with 4 on the crank and 1 on the cam 

We have removed the sensors ,its has 2 teeth on the crank which are equally spaced  180 degrees apart and 90 degrees before and after the sensor with the engine at TDC 

The cam is 100 degrees of cam angle before tdc 

Thanks Dave

 

[S2000 trigger scope]

Hi ,

having problems starting a s2000 engine ,the crank scope trace doesn't look like the 12-1  I was expecting .

Car was fitted with a Haltech E6X ecu and came in as a non runner 

Trace looks the same on or test scope

Thanks Dave

[Turbo Honda blackbird ecu]

Thanks for the reply ,sorry for the slow response unfortunately the chassis was delayed .We are experiencing some trigger issues .The engine is fitted with VR cam and crank sensors but runs very rough and shows around 40 degrees of timing scatter also when checked the crank trigger we see a different pattern on our separate scope (please see attached images)

Will be grateful for any advise

please find start up cal

[Cos yb start cal problems]

Having problems with a start  cal for cosworth yb turbo engine running Storm black ecu 36-1 VR crank sensor,GM 3 bar map sensor ,440 cc injectors,wasted spark ignition

Engine runs for around 30 seconds ,air fuel goes lean,seems to drop 2 cylinders and cut out .

Crank sensor trace looks good

I would be grateful if someone could cast their eyes over the start up cal attached

 

Thanks Dave

[Trigger offsets]

Hi ,

 I seem to be having problems adjusting the crank trigger offset ,the set up is 36-1 trigger wheel and no cam trigger .Trigger 2 is set to "none" engine sparks and has a injector duty but wont start .

Timing light is showing 110 degrees btdc

In the calibrate trigger section ,the trigger offset and the ref timing have a locked padlock which I have been unable to remove 

If I attempt Adjust the offset in the set basic timing section it always reverts to 0 

Any advise would be greatly appreciated 

Cheers Dave

[Turbo Honda blackbird ecu]

Thanks Simon,

 to simplify matters would it be better to have a missing tooth on the crank (12-1) and a single spike on cam and where would you suggest these are phased

Dave

[Turbo Honda blackbird ecu]

Hi ,

 thanks for the reply ,cam could be modified to `1 spike if necessary as we are refitting the standard cams  

[Turbo Honda blackbird ecu]

Which would be the best choice of ecu to run and turbo charged honda black bird with the following :-

12 teeth on the crank 3 spikes on the cam 

4 injector ,4 ignition outputs 

Boost control   3 maps 

Launch control with 1 magnetic wheel speed input 

ALS with egr

Thanks Dave

[MY2005 Sti G4+ exhaust cam target table]

Thanks for the info ,we now have the car in our workshops and have found that it doesnt have any wires in A1,A2 or A3 and has a 2007 ecu .It doesnt have exhaust Avcs either as the customer was lead to believe .

So the only issue is the AC ,if we change the pull up to ON in DIG 3 input  the AC clutch cuts in and everything works .

Any suggestions 

Thanks Dave

Hi ,

currently mapping a MY2005 Sti with exhaust avcs control but unable to find the control table ,also looking for the Aux out /inputs list for the AC control 

Thanks Dave

[High idle when AC is switched on]

Hi ,

 I am new top this forum and wondered if anyone has experienced high idle on G4+ plug and play on a Toyota Celica Carlos Sainz which is using the st205 system when the AC is switched on .

The AC idle step is set to zero but the idle lifts to nearly 2000 rpm when the AC is switched on 

Thanks Dave

[Mitsubishi Evo misfire/cut]

Hi ,

I am new to this forum and the Vipec product ,we are having a issue with a new Mitsubishi Evo 3 plug and play system using the internal map sensor and air temp wired into the maf sensor

All pressure and temp readings are good but I have a load based misfire above 12 psi of boost at which it misfires /cuts at 3500 rpm ,below 12 psi it revs through no problem .Ive put a fcd on the standard ecu ,retarded the timing and it runs ok

Ive restored all the factory settings in the Vipec and still has the problem ,all boost and rev limits are well above the point of cut

I would be grateful for any advise

Cheers Dave
