any one out there got some ecu info i want to find a ecu to fit my 94 wagon as i have fitted a td05 turbo ,and other mods my ecu is a 4 plug 3b ecu can i fit a sti ecu or wrx ecu that has been chipped and wil be set up for tdo5 turbo as most wagons have td04 turbo any help please!!!!!!!!!!!!!!!!!! its running at about 1.3bar at mo it will go up to 1.5 but get fuel cut ect

 

Get a Polar Performance chip... or any 4-plug ECU with the chip already fitted.

Or get a 275PS-rated STi v.2 "6K" ECU (if you can find one).

BTW, the MY93-96 MAP sensor is a 2.2bar rating, so you should hit fuel cut at 1.2bar... unless a different MAP sensor or a bleed valve/MBC has has been fitted by a previous owner.

 

last owner had fitted a super chip but not been good write ups on these mods there is couple of ecu on ebay with a chip will have a look thanks for help ps do you know if il get more gains by fitting sti injectors and upgrade fuel pump as well and should i have a fuel reg fitted ?

 

If you don't intend to go fully mappable ECU, then no point in changing injectors. The 6K and PP maps are designed around the std 380cc injectors, with plenty of fuelling headroom. What's more, the OEM TMIC lmits airflow to just before the point the 380cc's limit the fuelling.

An FPR not need at this level (so long as the OEM one is functioning fine).

A Walbro 255 pump won't go amiss though - as your exisiting one is prob a bit tired now due to its age, so the Walbro will give you "fit and forget" peace of mind.
