Hi Everyone,
This is my first post so hello to all :)
I have created this thread to get some advice about my turbo car
Basically I have a car somehow similar to Peugeot 405. It handles and weights(1200 Kg) same as Peugeot. I have changed the engine to 406 turbo charge engine (XU10 J2TE, you can find out more on it on linke below). It produce 145 Hp.
However I have had number of problems with it as follow:
· Keep blowing the head gasket. This is because the car uses a n/a,(naturally aspired) ecu which is made by bosch. The map is standard and it has lots of pre ignition and knoks which has lead to four time gasket blow
· Can not take it anything above 140 Km as the detonation goes crazy.
· Only premium fuel can be used in it. The fuel injectors are standard.
· The boost is limited
Despite all this I have got a 0 to 100 Km of less than 6.5 which is quite good. although i Should say that I have modified the turbo so maybe it produce more than 145 hp, maybe close to 200
So now after this long story, I have decided to buy a aftermarket ecu and maybe a map sensor to sort the problems out.
So here are the questions:
· What is a cost effective and good aftermarket ecu for my case which can also log data. I have had a look at motec and some others. Does this ecus all offer OBD as a standard port to access the ECU?
· Due to a reason which i do not want to disclose it, I do not have an access to dyno. So are there any other ways of creating a map, maybe on rolling road or using data logged by ecu.
· What do u think is the maximum potential of my engine? Can it produce something around 300 bhp?
I have gone far to get books and learn about engines and ecus as I really have a passion for both card and engine.
I will appreciate any answer.
Thanks
 
Hello and Welcome to TorqueCars.:bigsmile:
Hope you enjoy your time with us.

Have a wander round an you'll soon hit 10. :)
 
Try megasquirt or Apexi.

To cure the detonation you could lower the compression ratio of the engine or introduce water injection.
