Tom Harper Posted July 19, 2011 Report Share Posted July 19, 2011 More than 12 tables are required. On a link plus g3 upgraded to g4 the amount of tables (and therefore features) are reduced. This is a step backwards and Im starting to wonder if the upgrade was worth it. Surely its only a few 10s of Kb? 20 or even more would be more like it. On the car in question we are going to have to either delete anti-lag or individual cylinder 3d maps, where previously both could be ran simultaneously with more besides.

Jurgen Biggelaar Posted September 12, 2011 Report Share Posted September 12, 2011 Tom. Are you suggesting you do not have 12 tables on the G4's G3 now? Can you send me your .PCL Jurgen Quote Link to comment Share on other sites More sharing options...
Lawrence martin Posted September 22, 2011 Report Share Posted September 22, 2011 instead of starting my own wish list i also have this problem but have run out of tables on the link g4 xtreme i need to use 4d fuel but due to other tables active i cant use this table i would have thought a high end ecu such as this would have been able to use all the tables avaliable i dont even have motorsport functions enabled yet! off the top of my head i have dwell, iat correction, fuel1,fuel2, afr target, boost 1,2and 3, ignition1, then the tables for the a/c fan, idle etc Quote Link to comment Share on other sites More sharing options...
Lawrence martin Posted September 25, 2011 Report Share Posted September 25, 2011 but its crazy you cant run motorsport functions and have different boost levels or have multiple fuel maps its kind of pointless spending the money on an ecu that can do all this but at different times but not together i dont even want to use anti lag etc but just want my fueling to be correct and have 3 boost settings off 1 and 2 and it wont let me Quote Link to comment Share on other sites More sharing options...
Steve1436215419 Posted September 25, 2011 Report Share Posted September 25, 2011 We can only hope they hear our prayers but i wouldn't hold my breath. They have not so far so..... But yeah i agree completely. The tables get filled up very fast and if you want to run a 6 cylinder car with say individual cylinder knock control. 2 fuel and ignition maps. 2-3 boostmaps .... Well in the end you need to choose what means the most to you.... Its like i have to choose whether i want my car to run safe or fast. Cant do both.

Lawrence martin Posted September 25, 2011 Report Share Posted September 25, 2011 actually steve youve helped me out there i can run the knock using two tables instead of six as the rb26 only has two knock sensors which should free up a few tables  its still poor though that you cant use everything the ecu can do at once  thanks again Quote Link to comment Share on other sites More sharing options...
Steve1436215419 Posted September 25, 2011 Report Share Posted September 25, 2011 Yeah im doing it that way myself. Running a v6 with one knock table for each bank. Quote Link to comment Share on other sites More sharing options...
Simon Posted September 27, 2011 Report Share Posted September 27, 2011 We do hear you. The catch is that adding tables is no small task. The memory allocation for tables was set at the very start of the building of the firmware. To add more will require almost a total re-wright of the firmware. It is something we hope to be able to offer but it will be a long time away. Quote Link to comment Share on other sites More sharing options...

Josh Burt Posted November 28, 2011 Report Share Posted November 28, 2011 Not to pile on, but I am about to be in the same situation. I really want to pick up a knockblock and utilize individual cylinder knock correction. I also would like to run an E85 sensor which will need 4d fuel/spark maps. Can't do both together though Quote Link to comment Share on other sites More sharing options...
Paul1436215384 Posted January 5, 2012 Report Share Posted January 5, 2012 Just want to add that I would also welcome some more tables, because I'm also using some motorsport functions, and coupling that with knock control, etc, quickly eats up the available tables. I'm very glad to hear it's a firmware limitation, and not a hardware one. That means that, potentially, a future firmware upgrade could make more tables available.

Scott Posted April 10, 2012 Report Share Posted April 10, 2012 Hi Guys, The job is a big one, several thousand hours will be required. The memory on the current ECUs mean there just is not enough room to add more tables. The only way to increase the amount of tables would be to remove other features from the ECU. Scott.

Kurt Finearty Posted April 18, 2012 Report Share Posted April 18, 2012 Is there any plans to increase the memory of the current ecu line up ? Or a replacement ecu planned - enabling all features etc.. ? Â Quote Link to comment Share on other sites More sharing options...
Steve1436215419 Posted June 23, 2012 Report Share Posted June 23, 2012 So it is a hardware problem after all? Quote Link to comment Share on other sites More sharing options...
Scott Posted June 26, 2012 Report Share Posted June 26, 2012 Hi Steve and Kurt, The G4 ECUs (like all ECUs) have a certain amount of memory. The firmware uses up that memory. In order to add more tables to the firmware we would have to remove other features from the firmware. We are always working on new products including firmware and hardware. I can not say when more information will be available. Best regards, Scott Quote Link to comment Share on other sites More sharing options...
Tom Harper Posted July 5, 2012 Author Report Share Posted July 5, 2012 Glad im not the only one having this problem. To be honest, the way we have taken one particular car now, anything up to 30 tables would be more like it. Or to put it a better way, each and every feature 'should' be able to be used at the same time, like most other ecu's out there. I feel this is the only thing holding back link from total market domination and would have thought it would be higher on your priorities list, but I understand you are more than busy. I really do think it would be in your best interest, even from a financial standpoint. We are making do for now and Ill still recommend your ecu's over all others but it would be nice have more functionality. The code to lookup the tables must be there, so surely its just the space taken up by the actual tables? I know I for one would gladly take, for instance, a substantial decrease in internal logging capacity. Say 50%? I know the old honda ecu's used to manage with just 256k, and they used to fit many tables onto that. 2mb would mean lots of room for tables, wouldn't it? I understand how each lookup section would need to be re-written though, i dont envy the task. But it would get you more supporters.
