cheekymonkey Posted May 21, 2007 Share Posted May 21, 2007 Hi All It seems everything to do with BPU etc is all about increasing the amount of boost provided by the turbos, to get more fuelling and performance. Question is, is there anything else worth doing to a BPU car to improve the power at the lower end of the rev range before the 2nd turbo kicks in? Only thing I can think of would be higher lift cams, is this worth doing? Anything else? 4k RPM seems so far away when you're racing an R34!!

Nic Posted May 21, 2007 Share Posted May 21, 2007 Remapping the timing and fueling with something like the Emanage or Emanage Ultimate will give you some extra. Bigger cams will give you more power further up the rev range. Quote Link to comment Share on other sites More sharing options...
wkdtime Posted May 21, 2007 Share Posted May 21, 2007 It's not just about increasing the boost, a decat also helps in a big way, quicker spool up etc. Another option would be to install a piggyback ECU as most J specs will run rich when at 1.2 Bar and full decat...again this will help in spool up time and squeeze a few more horses out. Edit - As Nic said. Quote Link to comment Share on other sites More sharing options...

Would either of those be suitable for going single as well? My plan is to go single one day, (when the stock turbos blow up), but if I can get a piggyback ECU on there in the meantime to increase power a little bit, I wouldn't want to have to rip it out when I do go single...

Yes both are capable of running small to medium sized singles, the Emanage Ultimate would be the better choice though as it allows more accurate mapping. Ian C has made some impressive numbers running his T67DBB with the EMU. Quote Link to comment Share on other sites More sharing options...

In that case I'd personally go for an Apexi Power FC Standalone if you can get hold of one or failing that my second option would be the Emanage Ultimate. Edit- Too slow......

Bearing in mind I already have an autosport wiring harness (not yet installed) what would I need to buy to be able to fit the EMU? Just pricing this up at the moment - realise I'd need an expert to map it too Quote Link to comment Share on other sites More sharing options...

cheekymonkey Posted May 21, 2007 Author Share Posted May 21, 2007 Thanks for the PM Nic recommended 15500501 GREDDY E-Manage Ultimate 15901500 GREDDY E-Manage Ultimate Harness Kit 16401301 GREDDY E-Manage Pressure Sensor 16401406 GREDDY E-Manage Pressure Sensor Harness 15901504 GREDDY E-Manage Ultimate Injector Adapter 2 I see this comes with a "Harness Kit", now, how does this fit in with the main wiring loom, is it plug and play or do we have to cut wires? Reason I ask is that I now wonder if I even need my brand new wiring harness Quote Link to comment Share on other sites More sharing options...

cheekymonkey Posted May 21, 2007 Author Share Posted May 21, 2007 For what it's worth I got mine from http://autosportwiring.com/toyota.htm and the quality seems great. Fast and cheap delivery from the states too! Quote Link to comment Share on other sites More sharing options...
