gogo Member of team Kittens Member 609 Member For: 20y 10m 22d Location: Melbourne Posted 28/09/06 07:53 AM Share Posted 28/09/06 07:53 AM I wonder if Goldie has his AVC-R gear/boost setup?? Could be a really good idea. Might be easier to have a 'top end' map, where boost is a bit lower, and fuels a bit richer.. Might be the safest option!!!←This would be interesting - and good point - functionality is just not availbe through current edit software - doesn't mean it can't be done...

My opinions of running rich is 2 fold.. Fuel will help cool the pistons etc, and more fuel makes a engine less suspectable to detonation.Also, High RPM + 6th gear = Overspin the dyno.. Most Dyno Dynamics have 200km/h limitor in them. So high rpm + 6th gear will be way beyond that. tuning in 4th (1to1 gear) is fine.Danny.←You are absolutely correct Danny - and I do understand that - I guess the point I was making it just re-inforces the need to run the 'right' air-fuel ratio's and that the actual's will vary with other conditions and that this needs to be allowed for.the second point was that if I am correct the reason you make slightly higher boost in the top gears is you take longer to move through the rpm range, which enables more boost to build - this can be simulated on the dyno by adjusting ramp rates to be slower so it takes longer for the run - of course you need an intercooler that is up to the job, as well as cooling capacity for the dyno...

Keeping an eye on all those parameters would be a good method to gauge exactly what is going on, and can help avoid a nasty or costly incident in the future.

Not the reason.←Actually, No body corrected me.. I just fired up advantage, and Commanded Fuel is TP vs RPM, not Load.. the Spark map is Load vs RPM... shows how often I look at the headings So damn it, Gogo's original comment stands correct, you would run tp500 richer based on the fact that you will have more load in a higher gear..Although, in saying that, I also disagree. Load is calculated by manifold presure.. ie, boost.. Higher gear would generally load the engine more, and produce more boost.. But, we have a PCM controlled boost system here, not a VL bleed valve. So technically, load would be the same in all gears provided you are controlling the boost properlyWhat datalogger are you using?My logger shows I got peak load 1.7 with approx 12psi..Rule of thumb is load of 2 is 15psi.Not sure why it would say 100%d Link to comment Share on other sites More sharing options...

I believe its more due to the extra exhaust gases produced when the engine is working harder, in turn means turning the turbo harder, more boost. but pcm control boost control will open the wastegate more to stop it boosting more..However, in a manual VL for instance, you hardly ever see 15psi in first gear because as it comes on boost the engine revs too fast and you have to get ready for the next gear.. So your comment also does come into play.d Link to comment Share on other sites More sharing options...

When I say I reached 100% calculated load, you map Xede with load Vs rpm points, with tps correction. I drive along, watch load ( or data log it from 2 sources ) vs rpm and that's how I tell what load the engine is at in regard to rpm and boost/timing obtained. I don't have to worry about the tps correction, as wog has that sorted in the base edit tune. ( and Simon, as I'm stuffing around with one of his tunes atmo ) Although it makes for an interesting part throttle experience.... Like I say, I'm just learning my way around, on low boost to have a bit of 'fun' and see what does what..When you say a 'peak load' of 2.0, is this the boost setting you are referring to? ie, you want 16 psi, you command 2.0 load etc?Remeber I am only fudging the signal from the sensors, as a percentage or value, as to what the pcm sees.. I command a percentage of duty cycle from the wastegate solenoid for rpm v load on engine. I assume it's the same but different to sct edit?

Thus causes XX psi, which corralates to "load".. if you have 15psi, you have approx 2.0 load..the ford pcm (not advantage) has various tables for boost control.. allows open or closed loop boost control.Advantage only gives you access to the Fords PCM tables..D.
