2022年1月19日 · If you choose not to make use of VVT, its simply throwing away free horsepower the original engine designers spend millions implementing! Here’s a final sign-off image of an Mk1 Escort that featured an ST170, bike carbs, and our Nodiz Pro ignition system – both before VVT control and using a VVT Pro – the results speak for themselves!

The Ford ST170 which has factory VVT can lose over 40 lb/ft of torque without the VVT working - and traditionally before ECUs could offer correct, OEM like closed loop control, most would either lock the cams, or replace them - neither of which give the same return per investment as simply using the stock control system with a capable ECU such ...

Here we look at how Variable Valve Timing used on the ST170 works as well as how the new Motorsport Electronics VVTPro controller works. ...more. See here for a detailed write up and graphs:...

2014年2月27日 · After reading countless (mostly incorrect) posts on countless forums about how the secretive VVT on the Ford ST170 works, and how different methods of control with systems that can't really control it properly effect the power, we took it upon ourselves to create a standalone, mappable VVT controller specifically for the ST170 Zetec engine...

2018年12月8日 · Here's an interesting article on ecu control of the ST170 VVT system with graphs showing where these engines do actually produce peak power, and how much of it, on a proper Dyno Dynamics set of...

2016年12月5日 · according to google the vvt on a st170 is a simple on off type set up kicks in at about 3000rpm. you should be able to use the programmable output to switch the vvt on at your desired rpm. see section 13.10 on/off outputs.

ST170/Zetec/Duratec (and Ford Engines with a stock sensor) will run a 36-1 crank trigger, and require either 75 or 255 as their offset depending how the coils are wired. Vauxhall...

2019年8月16日 · Building: An st170 powered mk indy. The vvt pulley is sprung so should return to its home position when not running. Getting the bolt up to torque with out the centre of the pulley turning on the cam. You can’t use the timing bar to hold the cams as you will take a chunk out of the end of the cam and the centre will still rotate on the cam.

For some time I aspired to getting the VVT function working and this year bought a VVTPro and refitted the VVT cam mechanism. It comes loaded with a 2D map table (cam timing right even more of the time). It advertises the facility of a 3D map factoring in load from TPS.
