csimoes Posted November 1, 2013 Author Share Posted November 1, 2013 and what about some input about LPG spark tables? no? Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted November 1, 2013 Share Posted November 1, 2013 On the spark front, you haven't raised the low RPM areas enough, and have raised the higher RPMs too much According to the graph you shouldn't be adding anything to the advance above 4K, though you have, although not much. I think the last one is closest, but still needs more lower down and less higher up, albeit only by a couple of degrees. Quote Link to comment Share on other sites More sharing options...

Hybrid_From_Hell Posted November 5, 2013 Share Posted November 5, 2013 OK I have only tinkered a bit with LPG for a mate. He has a 3.9 std V8, here are the .vex Import table and a JPEG Picture of the Table I last did any work on This was Version 6, seemed to be a close performance to Petrol, had this as his LPG map. We haven't done anything to it since. Would be useful to have more Info on LPG here for others, so I'll kick off with my (Limited) efforts. By all means rip it apart if there are errors, as I said this was me tinkering and very much learning seat of pants stylee !! LPG_3.9_Prototype_6.vex To load .vex file : Save save to say desktop open Megatune Tuning / Spark Table (select which one you wnat it to load into) Import Tbale (select Vex file) Job Done Let the slating of me LPG efforts begin Nige Quote Link to comment Share on other sites More sharing options...
Bowie69 Posted November 5, 2013 Share Posted November 5, 2013 That doesn't look too bad at all to me Nige, only thing I did do was work out the cruise points on the map and jump them up a bit, just to help economy a bit, and seemed to work. If you wanted to be really accurate you should be able to modify your petrol table mathemagically based on the revised advance curve from the linked information above....

csimoes Posted November 6, 2013 Author Share Posted November 6, 2013 when i open TS a get this warning i've tried to find where it comes from but can't find it any ideas? 1 Warnings:Warning: MSQ Units Mismatch for RPM4S! 10000RPM/Sec or 70%Slip found in current configuration, 10000RPM/Sec or 70%Slip found in MSQ, values were not converted to new units.

csimoes Posted November 6, 2013 Author Share Posted November 6, 2013 finally started tuning with TS. after an initial run of around 20 minutes on easy, it allready change a bit there's one thing that i don't know how to interprete. when i take the foot of the loud pedal (what's the word for this situation, over run?!?!? deceletatrion?!?!) the car starts to pop pop pop a lot what is the reason for this pop's? maybe it's a stupid question but please be patient Quote Link to comment Share on other sites More sharing options...
elbekko Posted November 7, 2013 Share Posted November 7, 2013 That's that you're running way too rich and the excess fuel is igniting in the exhaust. This may affect your lambda readings when it happens. See what cells you're in when it happens and tone them down a bit yourself. Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 7, 2013 Author Share Posted November 7, 2013 it's happening in the lower Kpa 30 and undr around 1800-2500 (didn't go much higher then that). i don't have over run ful cut on, would this help with this situation? and isn't a advantage to have it on?

csimoes Posted November 10, 2013 Author Share Posted November 10, 2013 the poping situation is under control did one 15 minutes run on easy and then one 45 minutes run on normal and the car is runing great so far but i didn't get the upper/right part of the VE table. today went for another run on normal to try and get to that area. well... after 30 minutes of going up and down a 2.5 miles hill to really get to those hight rpm/Kpa i got this final Ve table, but i don't get how it went so rich?!?! i don't have a turbo... how can i tune that area without getting this strange numbers? inical VE (nige's) after the 15+40 and on the right the final one of today i'm using this AFR table on Tunerstudio Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted November 13, 2013 Share Posted November 13, 2013 You don't need to try so hard to get to areas of the table you'll never visit again - as long as it is close to the rest of the table and doesn't do anything too silly you're OK. If in doubt, ramp it rich towards the edges. Quote Link to comment Share on other sites More sharing options...

csimoes Posted November 23, 2013 Author Share Posted November 23, 2013 little update installed a innovate LC2 to see if can tune it a little better and easier. followed the installation instructions and changed the MS for wideband at project properties, and set the ego switch point for 2.45V is there something else to do?

AncientGeek Posted November 26, 2013 Share Posted November 26, 2013 Rather than use a switchpoint use the target tables. This allows you to go a little lean in the cruising area and also allows you to use Lambda correction right up to wide open throttle. Typical target at WOT is 12.5 Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 30, 2013 Author Share Posted November 30, 2013 update after a 50 minuts run on normal a got a much leaner map than i had, and could get "normal" numbers at higher rpm and MAP i used tune live and got one map but i recorded the run to using the MLV with the same paremeters i got a different map, a bit more leaner in most cells. now what map should i trust? with MLV with tune live Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 30, 2013 Author Share Posted November 30, 2013 another 50 minutes run on normal and i got this map what do you guys think about it? again the final result from tune live and MLV are diferent?!?!? if it is based in the same algorithm, why the diferent results???

Hybrid_From_Hell Posted November 30, 2013 Share Posted November 30, 2013 AFR Tables ? Also is your truck geared spot on ? as this wioll affect fuelling hugely ? Whats the G Box T Box ratio / CW&P and tyres sizes ? WB will retune FASTEr than NB, but often they will tune close if the parameters are matching, however you can tune a tuned engine and cells will still change a bit here and there. Clues maybe is which MSQ "Feels" better and why, does either run the engine hotter etc ? Interssting stuff non the less and congrats for keeping going after the install !! many just go "Yup thats lovely and fine ta muchly" Nige Quote Link to comment Share on other sites More sharing options...
csimoes Posted November 30, 2013 Author Share Posted November 30, 2013 afr table used it's this my setup is LT77/BorgWarner with 4.12 R&P and 285/75r16 the differences are minimal, don't think i'll be able to notice anything but just think it's strange that they exist. if tune live gives 77 MLV gives 76. being that tune live is allways richer. since i've installed it it's been my toy another thing i notice was that on the first runs i had the snorkel connected and couldn't get to high MAP at high RPM this last runs, with it disconnected the only cells i couldnĀ“t reach were the top/right 4 cells at 97kpa and above Quote Link to comment Share on other sites More sharing options...
