Aftermarket Ecu Query....

[BackStreetRacecars 3]

Right this may sound stupid (I start a lot of posts like this!!) but I presume that you can run any common rail electronic injector type diesel on after market management in the same way you can a petrol with t/bs or whatever? Does anyone know of anyone that does is or had done it in the past???

Not a chance I'm afraid. Common rail injectors are peak and hold, they take about 100 volts to open them and about 50 volts to keep them open... With several amps too!

 

There is only one aftermarket diesel ECu that I know of and it's certianly not affordable!

A petrol ECU simply doesnt have the correct inputs\outputs to control the common rail actuators and sensors.

At the rolling road where I used to work I used to fit Steinbauer PBOX this is not an aftermarket ecu, more a piggyback system, and on some cars it made me think about buying a diesel.

 

The pbox is not cheap starting from around £250 up.

ok cool... thanks fr the input guys... I have access to the tune-it type piggyback tuning device that plugs into the injector rail and had various settings... was just a shot in the dark really!!

not heard of many at all, all the high power diesel vehicles I've seen have run mapped standard ecu's more commonly than piggyback devices.

 

here's one I have seen, no price though

you can't use a normal petrol ecu (despite of the outputs/inputs) because diesel, just like direct injection petrol engines need perfect timing of injection.

a normal car gets its fuel trough every cycle, the time is not critical because it will stay behind the valve until its sucked in. but direct injection engines need accurate timing so the fuel gets in the chamber at a well defined time in the cycle. i think thats the main reason its so complicated, not the output-loads of the injector controllers.

What engine / ecu combination do you have?

 

I know I have a few .bin's kicking about that work on the bosch edc15 DW10 HDI engines. I have the 115bhp generic non I/C map, and the 150 bhp Intercooler map. Yours for beer tokens if you know someone handy with a kwp2000 and a laptop/pc

 

PM if your interested.

ooo sorry to butt in but ive just got a 306 hdi and was looking at these tuning boxes but i dont know much about them and cautious of the cheapish ebay ones and i cant afford a ecu remap although i heard you can buy a thing and remap it yourself if you can get the maps

anyone know much about these as id like a lil more boost out of it

thanks in advance

basicly as post above you need a kwp2000 a lap top and a map that seem to be floating about for cheap.

how safe is remapping it myself,dont wanna fry ecu or bugger my engine

[decoc182 0]

Providing the .bin is safe, and the laptop/pc does not crash or power off during the flash process its pretty safe. I flashed mine outside my local pcworld (after going to get the USB cable for £30 thieves! ) That was an awesome drive home

 

 

Tuning boxes, from what Im aware, trick the fuel pressure sensor value to the ecu, so that the ecu provides more fuel. Bit like an ebay resistor, but slightly more effective. Remap will always be better IMO.

who stocks the kwp2000 then?? or is it a question of... cheap ebay interface then decent program?
