Ideal issue

Hi guys

Seem to have a problem with my throttle control

I currently run syvecs piggy backed to the auto ecu

It seems the auto ecu is playing up does anyone know a good syvecs dealer as it looks like I need to go standalone

 

Tryed ryan but he's out the country according to the email I had back

 

Or anyone got a spare auto ecu I can try to see if it is the problem

 

This is the message I'm getting of the syvecs

I am nomSyvecs expert but that LOOKS like it is seeing an incorrect voltage to or from the throttle position sensor. Does the engine itself run OK? Is this a VVTi?

 

If it is a VVTi they suffer unreliability with the sensor on the throttle pedal and the throttle position sensor. The sensors have failsafe fetures and any slight sensor error will cause issues.

Is this with the engine running? The reason I ask is I'm pretty sure mine is yellow until fired up, as the voltages are incorrect until then. It's a while since I've checked though.

 

The reason, I'm guessing, for the piggyback is to control the autobox. Unless, as Chris has mentioned, you are VVTi?

Cheers for that will look at this

Where is he based ?? And will drop him a call on Monday

 

As with most mappers he travels all other and also like Ryan has the ability to do remote mapping and diagnoses, an issue like this could likely be solved remotely, I know he uses a few Dynos across the country including SRR.

On a side note, I see you are running an S6GP as piggyback, this was the solution for AT before the S6 Plus was released, you can upgrade an S6GP to an S6 Plus which means you could lose the stock ECU altogether, might be an option worth looking at it.

 

The upgrade isnt a complete new ECU, the GP carrier board is replaced with the Plus board and new case if memory serves me correctly.

 

Romain, Ryan or any of the Syvecs dealers would confirm and price it up if your interested.
