Simply Volvo Posted March 11, 2013 Report Share Posted March 11, 2013 No, like which values would it use when in WOT. Highest load on the load axis? Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted March 11, 2013 Author Report Share Posted March 11, 2013 No, like which values would it use when in WOT. Highest load on the load axis? What ever the load and RPM dictate. It is possible to be WOT and below 8ms of load. Link to comment Share on other sites More sharing options...
Simply Volvo Posted March 11, 2013 Report Share Posted March 11, 2013 Ah okay. I must be misunderstanding load. Link to comment Share on other sites More sharing options...
rick55_55 Posted March 11, 2013 Report Share Posted March 11, 2013 Ok, idiot question of the night. Is there a overboost/load table? If so is it the "Overcharge-Load" table? I set the pressure ratio map super high and it didn't really do anything. Pretty much stayed stock which is when i first give it WOT it spikes to about 13-14psi and the levels out at around 10psi. I am being real cautious with this and asking before i dig too deep. Link to comment Share on other sites More sharing options...

I am being real cautious with this and asking before i dig too deep. Set RPM diagnosis of overboost to 7500. Set all values of overcharge-load to 12. Report back with how those differences affected things. Link to comment Share on other sites More sharing options...

Confused at why you arnt seeing an increase in power, unless you didnt increase the values in the parts of the map you were driving in. Link to comment Share on other sites More sharing options...

I didn't change the Overcharge load table which would limit the load/boost Link to comment Share on other sites More sharing options...
Simply Volvo Posted March 11, 2013 Report Share Posted March 11, 2013 I didn't change the Overcharge load table which would limit the load/boost Makes sense now. Also raising or maxing Overchage load, and then maxing RPM diagnostics and load difference for overboost will effectively "remove" fuel limiters aka fuel cut.

Tightmopedman9 Posted March 11, 2013 Author Report Share Posted March 11, 2013 It turns out I made a mistake with regards to the load limiters. I removed two extraneous limiters and changed the Overcharge-Load to the correct offset. .xdf has been updated. Link to comment Share on other sites More sharing options...
Simply Volvo Posted March 11, 2013 Report Share Posted March 11, 2013 So now the only limiter is overcharge load? Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted March 11, 2013 Author Report Share Posted March 11, 2013 So now the only limiter is overcharge load? and RPM for diagnosis of overboost. Link to comment Share on other sites More sharing options...
Tightmopedman9 Posted March 11, 2013 Author Report Share Posted March 11, 2013 I just compiled a list of every map referenced by the main RPM axis. I am now working on seeing which ones will need to be modified if the RPM axis is modified and which ones don't matter. Also, as for scaling for a larger MAF, I think I just figured it out yesterday and it is quite simple. Just scale all three load axis's by the ratio of (old area)/(new area). It will decrease all of the load values, but no map modification would be necessary However, you would still be going over the maximal value of load unless you adjust the axis to go higher, which would require the modification of maps. Does anyone have a larger MAF they could test out? I could send a modified .bin for testing purposes. Link to comment Share on other sites More sharing options...
98glt-5 Posted March 11, 2013 Report Share Posted March 11, 2013 I already have a larger 960 style maf, I could get the bin file for you if you want, I just need to get it off my computer at work. EDIT - it's already been adjusted for the size. Link to comment Share on other sites More sharing options...
Simply Volvo Posted March 12, 2013 Report Share Posted March 12, 2013 A 610 ecu from a 98 s70 glt will work correct? All s70 glts are turbo I believe so that means m4.4 Link to comment Share on other sites More sharing options...
Yea-but... Posted March 12, 2013 Report Share Posted March 12, 2013 A 610 ecu from a 98 s70 glt will work correct? All s70 glts are turbo I believe so that means m4.4 Yes. 98 glts are all turbo and m4.4. Link to comment Share on other sites More sharing options...
