Fuel cut defenders

Recommended Posts

I have just done a new batch of these, and they tend to sell quite fast.

 

Since Greddy and TRL stopped doing their very nice and reliable fuel cut defenders I have been wondering about building a sensibly priced alternative. The great thing with the Greddy is it did not clamp the MAP sensor voltage until the pre-set threshold was reached. The HKS one was not so nice and skewed the output from the MAP sensor, thereby also skewing the fuel curve.

 

I have now tooled up to produce my own FCD that leaves the MAP sensor output *totally* unaltered until the voltage clamp threshold is reached, just like the Greddy ones did, when they were still available, but using more modern, closer tolerance components and a slight circuit improvement. It also uses the same colour wires as the Greddy, meaning the excellent on line pictorial fitting instructions at http://mkiv.com/techarticles/bcc/bcc_install/bcc.htm can be used to aid fitting, which is very easy. They come with an earth eyelet ready soldered on, meaning only three other wires to connect. Use the central stud or the main ecu to floor pan for th earth terminal, under the 10mm socket size nut.

 

They come pre set on lab standard equipment,to suit either VVTi or earlier TT models. If you have a VVTi or 1JZ-GTE let me know when ordering. I have 6 ready to ship, the last batch sold out very quickly. They can be programmed for other MAP sensor turbo engines like Mitsubishis, RX7's, Skylines, MR2 turbos, blah blah. If you can mention them on other forums where you may be a member I will be very grateful!

 

Price is £65 plus VAT with £5.80 plus VAT insured P&P to any UK

post code. That's £84.96 grand total. Please ask for a delivery

price to other places if required. Thanks.

I can supply wiring schematic for the VVTi if required. Just different ecu pins used, as easy to fit to a VVTi as a none VVTi engine, 4 wires to connect, one being an eyelet terminated ground wire like the none VVTi ones.
