Title: Electronic IDI pump, how to up the power?
Post by: aidan on April 30, 2008, 10:51:19 am

Ford Ranger/Mazda B2500, 2.5 TD 109bhp
Electronic IDI Zexel "eeprom" pump, no tuning box or chip available.
Engine does not run a N75 or equivalent, must rely on MAP and MAF?

As the pump is electronic, I can't adjust any screws to up the fuelling, will adding nozzles (if available) up the power as they do on a VW TDI?

If it's drive by wire then you may have to get a mechanical pump built up to be able to extract that extra power. If it's like a mechanical pump but with controlled elements in it then it may be possible to modify it. Unfortunatly you may have to send it here over the pond to either Giles or Tintin to have them have a look see.
If this is Aiden " Beaker" i',m sending that transmission you sent to be built up in 2 weeks. I'll let you know how it went.

Not the same person!

After more research, there are 'tuning boxes' available for it, £300+ and from the description; "4 or 6 wires and adjusted by turning a screw", sounds like just a resistor mod.

Any ideas?
