      Post Tuning Box - MI vs Rail Pressure

      Ok , so i planned on getting a tuning box for my ford Figo this month. I had read the thread on tuning boxes and remaps which proved to be a true find. After that i was sure i would get a Induction Modulation type of tuning box , but the problem is this , PRICE.

      There are a number of options in the case of Rail pressure modification type of tuning boxes , costing around 20K .

      But of Induction Modulation , there is only Petes that i found , the Petes box for the Ford ECU is IM type but costs 43.5k

      My question is this , is it worth the difference . Would there be a difference in real world performance? The Rail pressure could lead to more strain on the components involved , but even replacing the nozzles would not come up to the price difference .

      Here are a few more threads you can read.

      Guide to Tuning Boxes and Remaps
      Modifying a Diesel for Performance.
      Spider or petes...
      Ford Figo TDCi Modifications
      TMC Motorsport Digital Plug In Tuning Kits

      SUMMARY - the rail pressure boxes are very basic and rudimentary - and therefore cheap. They also make about HALF the power that the others make. Please compare the dyno/output figures (many of the rail pressure guys do not put this info up)

      The other boxes are much more complex , and the generate much more power (esp torque). The manufacturers of newer generation cars and are making their ECUs progressively more difficult to 'chip'. (multi channel, built in mechanisms to detect any 'modifications' etc). Hence these boxes are much more expensive to make.

      the nozzles dont fail with rail pressure modulation. atleast, not frequently.
      Its the rail pressure pump that goes. The pump itself might cost 20k, but you will normally have to change the rail and injectors along with it. the total bill may come up to 50k.
      I'm not saying the rail pressure TBs will cause a failure, necessarily, but I feel the risk is higher with a RPTB.

      The injectors on the Figo are Piezo injectors. They are not known to fail. but if they do, that can get expensive.
      I was told that the Piezo injectors are also the reason why the TBs are so expensive.

      Are you not considering the many remaps available these days? Pete's still have not decided whether they want to market the Figo remap, but TDI racing, and torque 7 are still available.
      That takes us back to the debate TB vs Remap.
      I'm still undecided on that one.

      +1. The rail pressure boxes are almost always pointless waste of money. If they dont develop sufficient power, what is the point in buying them?

      IMO, either get a remap, or get an Induction Modulation box.

      Check the remap route out too (- but may void warranty. )

      Technically a remap is 'more wholesome' - if done right . Speak with Peter I am sure he will point you in the right direction!

      Yeah kb100 , I have been contemplating a remap , but losing warranty is not worth it for me . Also o plan on changing only the TB and fixing a stock replacement filter that I have .

      Which one are you planning on using? If its K&N beware - it has extremely poor filtration characteristics! I used one for over five years and suffered! I have felt the OE ones were better in performance as well! Ripper may have something to add here from his experience.

      Oops.... The one I have bought is the k&n . The lOwer range rpm response had improved a lot with the filter , but I felt the top end had suffered . I'll put up in gear acceleron times to see . So kb100 , worth it to go for the green cotton after this ?
