steve whale Posted September 1, 2007 Report Share Posted September 1, 2007 hi, i recently bought the above as a secondhand unit,link hold their prices you know, anyway, i would appreciate anyones help with a couple of questions i have. The unit will be fitted to my mr2 rev 2 turbo,with 3sgte engine. I am pretty sure that this is an early unit,it has what appears to be a date on the side which reads 02/08/02,it consists of the main ecu,white box green/white label, a second box with "link 3sgte-mr2 adaptor loom" written on it,a serial link box and ribbon,and a sensor which i assume is an ait sensor(two wires one yellow,and one black,yellow goes to green yellow,black goes to black) Their is also a vacume port on the main ecu. Will this ecu enable me to remove the air flow meter? if so do i then leave the afm wiring plug disconnected? The guy i brought this from had sard 850 cc injectors fitted,and the ecu was mapped for his car, on comparison his and my cars are very similar except that mine has 800cc venom injectors, will my car overfuel and/or run very rich,or does the link have a safe base map that will enable me to roll to the tuners,if so does the base map auto cut in or do i manually (how?)set it. Lastly do i need a map sensor? if so does it have to be a link one? many thanks in advance to anyone who can help. Quote Link to comment Share on other sites More sharing options...
steve whale Posted September 1, 2007 Author Report Share Posted September 1, 2007 Just to add,ive opened the main ecu to read the chip details,they are as follows, n/o-1 says lpv10b 02/08/02 main board n/o-2 says sub3sgd 02/08/02 smaller board hope this helps. thanks Quote Link to comment Share on other sites More sharing options...
ashesman Posted September 3, 2007 Report Share Posted September 3, 2007 OK, so your ECU is a LinkPlus (G1) running V10b software. It is fitted with a 3SG trigger decoding sub-board. As far as injector sizing goes, your engine may run a little lean (smaller numbers to allow for the bigger injectors). There a re a number of other factors including fuel pressure that will affect how rich/lean your engine is. I suggest getting it to a tuner, then plug the ECU in... You can leave the AFM or remove it if you want, the ECU doesn't care. You need to run a vacuum hose to the ECU's on board map sensor. If you want to run more than 22psi boost then an external map sensor will be required...

steve whale Posted September 5, 2007 Author Report Share Posted September 5, 2007 hi ashley, many thanks for your prompt and in depth help. hopefully i have fuelling sorted out with an adjustable dial indicator type fpr, dual feed,overbored fuel rail and a walbro 255lph pump. i will follow your advice and get it to the tuners to get it all set up. great to know the unit has an inbuilt map sensor, many thanks once again, regards steve.
