Thanks headsex was a good read. I know little on the technical side of tuning however I'm keen as mustard to leard more. In terms of the standard calibrations pulling out timing...is this initiated by the knock sensor? What happens about tuners who turn off the knock sensing capability? I gather the calibrations include some sort of twin spark table that the base table hangs off so to speak? Link to comment Share on other sites More sharing options...

On the BA's they are way to active, and pull too much timing out. BF's are much better in this respect, although I do modify them as well.The Knock sensor Gains on the BA's knock detection needs to be adjusted, so far I'm not 100% happy with it, but im 90% there. There is no twin spark tables as LS1's have, its decides how much spark to pull out based on how "loud" the detonation is. There is 2 tables which limit the Max spark retard based on RPM, and another "slow learn" knock spark retard limit table (which is "like" a learning table, but not exactly). Out of interest, the BA F6 allows a maximum of 12 degree's timing to be pulled out.The timing is getting pulled out due to the Intake Air Temp correction table. every X degree's it is above 100F, it pulls X degree's out..When I get a chance, I'll upload some screen shots of the Intake Air Correction Tables (there is 2 which work together) and explain how they work..

Not having the software myself, it's very hard to understand how the calibrations interact and there is very little information available. However you are helping in a bit way, cheers! Lucky I got a big cooler etc on it's way to perth, anyone want to buy my wogcooler lol. Link to comment Share on other sites More sharing options...

I used to live a stones throw from that new dyno location. Thankfully my olds are still there however Nice one Danny, good read that. Link to comment Share on other sites More sharing options...

phildub Member 52 Member For: 18y 4m 14d Posted 08/02/08 12:21 PM Share Posted 08/02/08 12:21 PM Danny I guess this is why Nizpro use a thermostatically controlled water to air intercooler on their engine dyno when doing calabrations for these and other engines.This is so they can map the engine at a constant air temp and once fiished go back and check all different air temps and the amount of ignition timing correction that is needed. I believe they also can do this for both the water and oil temp as well. I doubt you will see this on a chassis dyno but Mario's sound very good.

Sounds like you are progressing this tuning hobby to perhaps a real job/career?So you are now advancing from car park & street tunes to dyno tunes?Are you using the SCT Flasher or Snipper these days?You need to see the Dyno room setup @ Tunehouse. Let me know when you are next in Sydney and I will take you in for a tour. Link to comment Share on other sites More sharing options...
