Chris Wilson Posted September 4, 2014 Share Posted September 4, 2014 No, depending how it's wired and designed it can influence other things! This HKS device in situ with a speedo converter could have many other implications. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted September 4, 2014 Share Posted September 4, 2014 So potentially, it isn't the 'speed limit defencer' that is causing these issues with kickdown, it could well be the speedometer converter. Quote Link to comment Share on other sites More sharing options...
Pete Posted September 5, 2014 Share Posted September 5, 2014 I thought that, but doesn't the speed converter just affect the speedometer? There's a stack of other devices that use the speed signal. ODO, Speedo, Gearbox, ECU, Traction control, Active spoiler etc. Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted September 5, 2014 Share Posted September 5, 2014 So basically, when a speedometer converter is fitted, the car is moving 1.6 times faster than the ECU is being led to believe? (kmh v mph) So even with the SLD potentially locking into 4th gear at higher speeds, it is still potentially possible for the ECU to drop a gear in what it mistakenly believes to be a 'safe zone' in engine RPM? If this is the case, then surely the best solution is to not fit a speed converter, and either fit a new dial face, or fit an auxilliary GPS speedometer that reads in MPH?

j_jza80 Posted September 23, 2014 Share Posted September 23, 2014 After a bit of deliberating, this is my solution... A set of MetalMonkey dials, with the scale altered to read in MPH without the need of a converter. It only read to 130mph, but a mechanical speedometer is next to useless above that speed anyway, and nothing GPS can't solve. So as far as I'm concerned, changing the dial face and using the HKS SLD II effictively cures this issue. I will test this over the next year.

Pete Posted September 30, 2014 Share Posted September 30, 2014 a mechanical speedometer To be pedantic, it's an electronic speedometer with an analogue face. Let us know how it goes. Quote Link to comment Share on other sites More sharing options...
Chris88 Posted June 1, 2015 Share Posted June 1, 2015 I realise this is a bit of a thread resurrection but I've read through more than once and I can't convince myself that anyone has managed to successfully delimit an Auto VVTI. Has anyone actually done it without replacing the factory ECU, what level of success did they have and most importantly, what did they use to do it?
