Decided to have a dig around in the inpreza to check some things. Took the cover off the ecu to see if it had been labelled up as to what kind of ECU/piggyback it had ,as its been remapped.

Only thing I could see was an old looking sticker with "royal motorsport" on it. ever heard of them ?

anyway. Is there anyway of plugging a laptop etc into the ecu to check what kind of software is on it ??

Going to get a remap soon and need to know whats already on it so I can tell the tuner.

its a 93 wrx import BTW.

 

I guess it's soldered into the spare area on the ecu?
I would expect them to be anothe rJap tuner like Bozz and Mines.
Do you know what power you're running at the mo?

Post a piccy up of the item that may get a few more responses

 

If it has been chipped then it will be mounted/installed here:

Apart from a ESL Daughter Board this is as far as you can go, other option is to get a aftermarket ECU, see here:

This is a picture of the outside of the ECU


And one of the daughterboard


can anyone enlighten me as to whether this is aftermarket or standard ?

if its standard then can anyone enlighten me as to how the car could be running over 1 bar of boost and how I dispatched a 300bhp scooby a mate owns with relative ease.

The only other mods I know the car has is a K&N filter , a de-cat ,and a group N exhaust. possibly a walbro pump but I'd need to check.

any help would be great. Need to know what I've got infront of me before I go spending any more money on it.

 

Standard ECU with aftermarket chip, not a 'daughter board' mate, will be simlar to this one Products
The daughter board is further down the page.
And heres the expected gains from such a chip

b13bat .you are a fountain of ecu knowledge.

thanks for the info. certainly helped clear a few things up. much appreciated.

 

Yeah no probs, I have the same car with same-ish mods inc chip
One thing I would advise is to get a AFR meter (if not already fitted) to monitor your fuelling when on boost as you cannot verify the program on the chip. A narrow band will suffice though some will argue you need an expensive wideband. If you run lean on boost you risk melting a piston, not good

 

Its got an AFR fitted too. Can see why its been fitted now. thought it was just a gimik

Was gonna remove it as its a pain in the a**e and it lights up like a christmas tree but I reckon I'll be leaving it in till I get a piggyback ecu or a new ecu fitted.

 

Sorted then
