Mark1104 Posted September 23, 2018 Report Share Posted September 23, 2018 (edited) Hi guys, I'm Mark, a new member of the Link forums. I purchased an old ST185 Celica GT-Four with a matching Link pulg in ECU of a similar era (early 1990's. Its been a steep learing curve to get the car running again, having been parked up for 13 years. I'm trying to identify which model Link unit it is and to find out if it will talk to a laptop. I have the led display hand controller but that only allows access to limited functions and is not ideal for displaying data on the fly. I have detonation problems at higher throttle settings and on boost. Tried pulling back maximum advance with minimal effect. Tried increasing master fuel a little with little effect. Perhaps its as simple as increasing fuel at higher throttle positions to allow for fuel supply as the boost increases. I'm installing a new fuel pump to make sure there are no fuel starvation issues that may be causing lean-ness. Inj / Oxy display tells me injector capacity and in theory the mixture but I'm struggling to make sense of the oxy display. It ranges 0 to numbers in the 90's but I'm not sure what the units are and what they mean. What units is this measured in (I expected 0-1.0 volt as a measure of air/fuel ratio). Any comments or assistance would be appreciated. Mark Edited September 24, 2018 by Mark1104 add extra information Quote Link to comment Share on other sites More sharing options...
