Sorry if this is posted somewhere else but I couldn't find a definitive listing of what the defaut settings for Evoscan should be.

Here's what I can add to start with:


Units - Metric (Kw/Nm)

Factory Vehicle Weight : 1588 kg(PFL Legnum Type-S with 1/2 tank fuel and all fresh fluids)
People Contents Weight: 92 kg (1 x Fat Guy at 14 Stone + boot content)
Tyre Diameter: 63.2 cm (PFL 205x55x16)

Gear Ratios:

1st - 3.789
2nd - 2.057
3rd - 1.421
4th - 1.000
5th - 0.731
6th - 0.000 (We can only wish for a 6th gear)
Final - 3.684

Frontal Area of Vehicle : 2.2 sq.m
Wind Tunnel Drag CoEfficient : 0.29 Cd (Galant)
0.31 (Legnum)

Atmospheric Pressure: ? (99.9 kPa is default in Evoscan)
Ambient Temperature: 15 deg. C (Average for current time of year)
Dyno Correction Factor: ? 1 (99.9 kPa is default in Evoscan)

Injector Scaling : ? (513 is default in Evoscan)


Please add any variations for the other trims/gearboxes/bodyshapes and also let me know if you think anything needs to be amended. Is it also worth noting the best set of items to log?

Edit1: CoEfficient Updated - Thanks Brad

The 0.29 figure is for a Galant, and I don't know what kind of Galant it is for. The front bumper can impact on aerodynamics hugely. I think .31 is probably a more accurate figure for a Legnum.

Updated first post. Brad I have wider tyres and the CF bonnet, do you think this will effect the Cd much? Oh there's the new FMIC too, not sure if that affects the dynamics.

Wider wheels do affect CD, but if they fill out the arches better (which they do, they are a better offset and bigger OD than stock) they will lower CD. I'd say it would be about the same.

The intercooler shouldn't affect it too much at all, the stock one is fairly restrictive and most aftermarket ones are a bit more open, although bigger.

As for the bonnet, I know that one change from EVO 7 to 8 was to reduce drag with the bonnet vents, and that the GT-A EVO 7 had no vents at all to further decrease drag. I'd say it will increase drag, but you will be getting much better cooling from the vents so it isn't much of a tradeoff.

Does anyone know if it's possible to log using Evoscan without the dash lights flashing when you are stopped ?

There is a option in one of the pull down menus that does stop the flashing but when that's ticked Evoscan can't connect any more, and just keeps re-trying and failing.

If you have a geniune tactrix cable the lights stop flashing when your in motion

Mine does that though John and I paid about 11 quid for my cable

Yes they do stop while I'm in motion, but how can you make them not flash when you are stationary?

You can't.
When logging and the car is stopped they will flash.
When logging and in motion they will not flash.
Menu item to disable flashy dash does not work on Galant/Legnum.

Just a note on the final drive ratio. I haven't managed to find out if this applies to our cars but i understand that a lot of 4wd cars that use a viscous center diff have a different front and rear final drive ratio. This is done to make sure there is always a speed difference across the center diff which makes it react properly.

Any ideas?

Beastlee

We don't have a viscous centre diff do we?

We do

Good thread ... I have started using Evoscan again and was wondering about these settings so that I could try a power run :thumbsup:

Beastlee
26-08-2009, 09:14 AM
We do


Cool, but doesn't that mean we have rear wheel drive that shifts the power forward when slipping on the rear?

Not really. We have a 50/50 split normally but under hard acceleration it goes towards 40/60 F/R

Bradc, what's your source for this? I had always assumed we had a similar setup to that which Jeff Lucius describes on Stealth316 (http://www.stealth316.com/2-awd3.htm#cdvcu) i.e. 50/50 normally but then 45/55 when there is differential rotational speeds between the F/R axles.

Guess we'd need to take the transfer box apart to confirm!

the settings described in the first post, how necessary are they, i was under the impression they did not matter unless you were trying to do BHP runs calc, etc.

they don't effect the logging of sensors stuff do they.

Phosty - I've seen two dyno graphs that confirm the front and rear operate like that, one of them was Gowf's

I'm not sure what would happen on the road with an identical tyre rotation rate

They are only needed if you want to do power runs.

According to Merlins tuning guide the VR4 injector scaling factor is 410cc/min. However using his XML definition file for ECUFlash, I get 409cc/min from my 20030011 ecu.

But I think only the estimated ECULoad uses injector scaling - does the Power run use the estimated ECULoad too?

Major Bump!

Nows the time to get these values correct, Hamish (EvoScan developer) is getting ready to release a new version (there's some sweet new features for tuners!) and he's asked me to email him over our "definitive list" of settings to add to the list of presets.


50688

As you can see, only 3rd gear is now taken into consideration for power runs / calculations. This is what I can fathom from collating multiple posts;

Common info (used across all cars)

People Contents Weight: How much you weigh, 10 Stone = 63.5 KG, 15 Stone = 95.3 KG, 20 Stone = 127.0 KG

Galant (Saloon) specific

Factory Vehicle Weight: 1520 kg

I am pretty sure those weights are dry, and I thought that the saloon was 50kg lighter than the estate....

I have had an auto prefacelift legnum VR4 with leather, half a tank of fuel and a small spanner set in it (5kg tops) and it weighed at 1660 kg. That was with no-one inside it.

I'm sure Nick is right the Saloon will be 50kg lighter than an leggy , and I would say a manual will be 50kg light than an auto - all weights will be dry

foxdie

Bump, anyone able to confirm the above weights please?

But you running that setup or you find some more info??

I'm willing to do a few runs on petrol and then on LPG, I'm right of thinking that should give me some fairly good comparison?? it may not give me the accurate power outputs but it will show how car lose/gain on each fuel??

weight taken from this thead,
http://www.clubvr4.com/forum/showthread.php?31415-Gross-weight-og-VR4&highlight=weigh+bridge

i got my old auto VR4 weighed and it was 1790Kg
car
me:- 110kg (at the time)
fuel:-full tank of fuel 45kg
tools:-30kg
fluids:- 20kg approx, about 17L of oil and 9L coolant and 1L brake fluid for and auto in total, (5l engine oil, 10L ATF, Trans Case 0.67L, Diff clutch packs atf 0.75L, diff gear 0.5L, ayc atf 0.75L, coolant 8-9L, brake fluid about 1L)

obviously the tools and fluids are a bit guestimated and are probably a bit under.

1790 - (110+45+30+20) = 1585kg

which isn't a bad estimate as the other thread recons a legnum type-s is 1570kg
