Igor Polshchikov Posted February 11, 2015 Report Share Posted February 11, 2015 Hi, I recently bought a Link G1 with a "WRX ROAD 97" chip in it. The chip reads: MC68HC711E9CFN25C47MSSFA9949 The board reads: Link  1996 Subaru v3.2My question is, can I use a module and a laptop to connect to it? If so, what module and what software? If I can't use a laptop, what can I use and where do i get / buy it? Thanks!  Quote Link to comment Share on other sites More sharing options...
Simon Posted February 18, 2015 Report Share Posted February 18, 2015 Hi Igor  That unit is hand control tuning only. It can be upgraded to PC tuning via a SerialLink but would need to be returned to us for that upgrade. Quote Link to comment Share on other sites More sharing options...
Igor Polshchikov Posted February 18, 2015 Author Report Share Posted February 18, 2015 Hi Simon,  How much will the upgrade cost and how long can it take?  Also I live in australia, what country will I be posting it to? Thanks. Quote Link to comment Share on other sites More sharing options...

Simon Posted February 25, 2015 Report Share Posted February 25, 2015 If you go to http://www.linkecu.com/support/returns-policy this will give you all you need to return the unit for the upgrade. For the manual this can be found http://www.linkecu.com/support/documentation/g1-engine-management-documentation/MY96Manual Quote Link to comment Share on other sites More sharing options...
Igor Polshchikov Posted March 2, 2015 Author Report Share Posted March 2, 2015 Thanks for that. Would it be appropriate for me to ask in a topic if anyone here has a second hand controller that they can sell me? Quote Link to comment Share on other sites More sharing options...
Igor Polshchikov Posted March 17, 2015 Author Report Share Posted March 17, 2015 Hi again, I have obtained a hand held controller. While setting up the TPS SPAN the value doesn't change while depressing the accelerator pedal. The manual says to adjust it to 100 while depressing the pedal and then let it go and re adjust down to 10, but is the value on the screen meant to change in response to depressing the pedal after the procedure has been performed? Also, when setting the idle rpm, there is no change unless I change the solenoid duty cycle manually. The idle just sits on around 1000rpm. Can that be because the throttle position sensor is damaged or not adjusted to hit the idle switch?  Thanks Quote Link to comment Share on other sites More sharing options...
Simon Posted March 18, 2015 Report Share Posted March 18, 2015 It the TPS is not reading 10 (closed throttle) then the idle control will be locked out. It could be that the TPS has been set up on a car that had the 5V and ground swapped. It could be worth doing a full reload to start from a known point.

Igor Polshchikov Posted March 18, 2015 Author Report Share Posted March 18, 2015 Is it expecting 4.7v on closed throttle? Is it looking at all at the idle switch (4th wire on the TPS) or just looking at the initial start up voltage? Â I tried reversing the ground and 5v on the connector to the TPS, doing the same thin. Just sits at whatever value I select at the TPS SPAN and wouldn't change on throttle opening. Â Quote Link to comment Share on other sites More sharing options...
Simon Posted March 18, 2015 Report Share Posted March 18, 2015 It only looks at the 0-5V signal the idle switch is not used at all. The TPS should move with the voltage displaying 10 at idle/ closed throttle and up to 100ish at full throttle Have you tried a reload?

Igor Polshchikov Posted March 18, 2015 Author Report Share Posted March 18, 2015 Yes, I have reloaded with no luck. Which ecu pin is it looking for signal on? Pin 3 on the little connector? Quote Link to comment Share on other sites More sharing options...
Igor Polshchikov Posted March 18, 2015 Author Report Share Posted March 18, 2015 Sorry, pin 2* on small connector? Quote Link to comment Share on other sites More sharing options...
Simon Posted March 24, 2015 Report Share Posted March 24, 2015 TPS is on the 2nd biggest connector. Pin #68 Looking in from wire side it is The Right hand most connector Bottom row 5 from the right.   Quote Link to comment Share on other sites More sharing options...
Igor Polshchikov Posted March 24, 2015 Author Report Share Posted March 24, 2015 Oh, thats different from stock. If possible, could you please post a picture/schematic of the pinout on the ecu? I now start to wonder what else is connected not quite where it should be. Quote Link to comment Share on other sites More sharing options...
Simon Posted March 24, 2015 Report Share Posted March 24, 2015 That is a worry as the plugin is geared to accept a stock wiring loom. Your ECU has just 3 connectors? Quote Link to comment Share on other sites More sharing options...
Igor Polshchikov Posted March 25, 2015 Author Report Share Posted March 25, 2015 Thats the problem I think, mine is the 4 plug.  Quote Link to comment Share on other sites More sharing options...
Simon Posted March 26, 2015 Report Share Posted March 26, 2015 Im a bit concerned the Chip is incorrect for the ECU. Was the WRXROAD97 on a sticker on the chip? Quote Link to comment Share on other sites More sharing options...
Igor Polshchikov Posted March 26, 2015 Author Report Share Posted March 26, 2015 There was a sticker but it came off the first time I changed the ECU box. Definitely read "WRXROAD" and 90% sure it said 97. If its any help, there was another number on it reading 449.  The car is running ok, but if the chip is wrong what are my options? Quote Link to comment Share on other sites More sharing options...
Simon Posted March 27, 2015 Report Share Posted March 27, 2015 If its just WRXROAD that will be ok. The later ECU for the 97/98 wrx had the chip WRX97 So you should be OK I think. On the 4 plug, your TPS comes in on pin 55 This is on the small plug top row 2 from the right. Â Quote Link to comment Share on other sites More sharing options...
Igor Polshchikov Posted March 27, 2015 Author Report Share Posted March 27, 2015 Sweet. That's what I thought. Is it absolutely necessary to have it seeing the tps? Its not reading it but seems to run and tune ok. Just sitting there on 10. Quote Link to comment Share on other sites More sharing options...
Simon Posted April 1, 2015 Report Share Posted April 1, 2015 From memory it is purely for idle control. Quote Link to comment Share on other sites More sharing options...
Guybrush Posted June 2, 2015 Report Share Posted June 2, 2015 Hello I need some info on this link ecu.I know its G1 but what version? Does support launch control? Thank you. Quote Link to comment Share on other sites More sharing options...
