no problem dude.

OK, this is a piss poor picture out side CFT by the bays. It was taken on a camera phone so I could see the stance of the car after the allignment. I get alot of request to show a pic of the entire ride but since i'm not done with it I've been hesatant on doing so. But against my better judgement I decided to give you all something to look at. It's very grainey but you can get the idea.

conservative Hp numbers. you must be pulling lots of timing. . .

xbgod · 01-12-2011, 09:31 PM

Thats what Rolo said.

VVTI is off and Microtech is still the main ECU right now. I have a Haltech unit coming in still but untill I get it I'll take the numbers I got.

Congrats on some real nice numbers. Looks like it went very lean above 4k?

What was your boost on that pull?

How come it stops making power at 4200 rpm?

xbgod · 01-12-2011, 11:16 PM

23 PSI on that run.

Using Torco 107 octane and VP M1 Meth.

Also still have not used nitrous yet. Just incase someone asks.

Going to go like this for 2,500 miles then try out the nitrous.

youre looking at the torque curve garm.

PETERPOOP · 01-13-2011, 12:10 AM

Very lean!

Nice numbers though. Couldn't imagine what 300+ whp feels like in a yaris.

Tuner needs to tune better.... you will have much greater numbers.

Sorry you are wrong here, richer mixture isn't equal to greater numbers infact it's the opposite way.

The best mixture is 14.7 stoich AFR and XBG map is going above it at lowest and highest rpm. So he is getting the maximum numbers he can achieve... richin the mixture makes the numbers lower but prevents damage to the engine

To Yoda... I think the conversion was made to account for the octane rating.... since at 3K rpm he's about maximum rich 10.

Parmas · 01-13-2011, 01:12 AM

I agree the map is too lean even for low boost above 4K. Increase fuel you are risking the motor life drastically.

Also if that was my dyno I would just shift at 5300rpm... after that you are loosing power and time.

Yoda · 01-13-2011, 03:23 AM

I see you are using Torco 107 octane. Was a conversion used to account for that octane to show in the afr? I am using 100 octane so when I see for example 13 afr on my gauge its actually running a bit richer than that. There is still lots more power I feel you can extract from it cause its way lean in the upper part where you power band just levels off. Very good job tho Xb! Thanks for contributing

stoich yes, at WOT no, better down around 12. Dyno pulls are done at WOT.

I forgot to mention 12 AFR for boost and lower AFR for high boost in case of boost spikes.

Ehhhh, Sweet spot is around 11.* for turbos and theres a bunch of reasoning behind that. Of course you can lean it out and make power, but aiming for stoich, really? you will make more power from having a proper afr and more ignition advance.... Safer too.
