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

I hope I have posted in an approperite section

Not sure about your specific car, but you absolutely should not be running a vehicle hard with a turbo charger if you don't have the correct ECU or a legitimate tune. It's by far the easiest way to destroy the engine. Most OEM Ecu's on cars that are naturally aspirated from the factory will be completely confused by the presence of boost, and will not adjust timing or increase fuel to compensate for the increased airflow. This causes you to run lean, misfire, and eventually make some impressive holes in your engine block.

You really need to register on a Peugeot forum to get the answers you're looking for. This site, while useful to a degree, has mainly US members. Peugeot doesn't sell cars here, and 99.9% of the people here don't even know what a Peugeot is or even what country they're made in.

My recommendations:
-Stop driving the car hard, do not enter boost at all. It will run fine out of boost, so you can still drive it.
-Install a wideband o2 sensor.
-Figure out an ECU solution for your application. There are many "universal" standalone ECU's, however they're not easy to use and will require a professional to tune. You might be able to use a MegaSquirt setup. Motec is ungodly expensive, way more than you should need.

A Peugeot 405? That car is from the 80s!

linux44

thanks guys.

It was interesting to know that there are not many peugeot in US. Here is full of them. In fact, I gues UK may be producing them as opposed to France

about the post that say 405 is from 80s, I know, I am a bit behind

I will try a good peugeot forum. By the way do u know if ecu mapping can be done without a dyno as I asked earlier? for example an ecu log or rolling road
or do after market ecus normally come with an OBD port to configure them

OBD is usually for emissions only, you can't program an ECU over OBD except in very specific circumstances. You can get a tune without a dyno, many people do road tunes. My car is tuned on the road with my laptop. Usually aftermarket ECU's connect via USB or Serial-USB converters to a PC.

linux44

That is really great. If i could tune it on the road. About the OBD, as I am new to these things, I though OBD can be used to remap or... and that is why I was asking.
I was planning to buy a wireless OBD to use it with my iPhone which I guess I may not do.

Does this mean , those remapping companies use a serial cable or a chipset ? I am asking because there are number of chinese seller on ebay whom sell a bunch of cable and software which is used to remap the car by using the OBD port

You need to stop beating on your car with a NA ecu.

You need way more fuel, you also need less ignition timing.

You are correct, the fuel presure is a must for my car, although I have played with that with the standard ecu by hugely increasing the fuel amount. I think I am getting about 15 Mpg.

It's a trap. Don't buy any of them. They're just making a quick buck by selling crap to an uneducated consumer. You really need to find a car-specific forum. All I can tell you is to look up MegaSquirt, it's the cheapest and best standalone ECU, but it's a total ***** to get working. Welcome to the world of turbocharging cars that aren't usually turbocharged. It's a long road, ask me how I know...

Peugeot used to sell them in the US. Once in a blue moon you can still see a rusty 505. There was a version sold in Latin America called "Evolution". Coincidence? I don't think so (OK, maybe yes) .

This^.

Truly, the best option for you would be to use the injectors, fpr and ecu that the car is supposed to come with and start from there. Otherwise you'll be pulling your hair out.

Peugeots are junk.. you guys shouldnt miss those things in the U.S.

I was careful with my wording. They don't sell them here anymore, which is correct. And while they did sell them they sold so few they really shouldn't have bothered. For damn good reason too.
