More Tables

Posted by Tom Harper at July 20. 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.

Tom.

Are you suggesting you do not have 12 tables on the G4's G3 now?  Can you send me your .PCL

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

Its been wished for several times, but its like talking to deaf ears.

I need more tables too but have to make compromises instead. Its a shame really...

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

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.

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

Yeah im doing it that way myself. Running a v6 with one knock table for each bank.

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.

For you Ross I sometimes do!

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 :(

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.

Yep. Now if we could only convince them to start from "scratch" again to get some more maps in there.
How about we show up on the Link HQ driveway with posters and stuff and chant slogans at them?

Maybe we can start a "work on the weekend" fund to get these guys going.

 

How many man hours would it take to get this firmware re written?

Re: More Tables

Posted by Scott at April 11. 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.

Is there any plans to increase the memory of the current ecu line up ? Or a replacement ecu planned - enabling all features etc.. ?
