boosted hybrid

I tried front, rear and time based boost control this past season and ran my 8.9 pass with front VSS based boost control with 8 load points on the table for resolution. I had probably the most basic/simple boost control set-up. Boost control is important, but chassis and power management is probably more important.

what are the load points based off of to make boost changes?

Sorry dont want to thread jack.Can this be done using S300 to?

dont think so. you cant change the tooth settings in s300.

You tried it on your car? I have actual data from my car at the track and it’s very consistent from run to run. I adjusted my setting in the aem to match the data coming from the sensor. Works very well, you just have to know how to set it up and know what to do with it, i dont need to have more resolution for what im using it for.

exactly, more resolution is great...but isnt NEEDED to get it done. I setup mine in the Haltech, and I actually am going to have to cut off a few teeth as there is TOO much resolution on a stock ABS ring gear.

Dont forget who gave you the idea for calibrating your rear wheel using the dolly...lol

You cant change the tooth settings in the s300 software...but you can change how many teeth it physically reads by cutting them off the ABS ring

It would never be perfect, but with a little math and testing...you should be able to set it up pretty close.

i was just thinking about that after i posted that. would you just count the number of on off's and just start with how many times does the stock vss pulse per revolution and try to get the abs ring to have the same number of on off's per revolution?

I had it on my car, yes. I run high resolution for the front and rear. I have yet to dial it in. That's what I'm hoping to accomplish in March.

4wd dyno......that's all Iam sayin

Last I checked most dynos if they are 4WD are independent of each other. So no power to the rear than no spinny. haha

But however there are some that are mechanically coupled between the two just have to find one.

Rtype16

Yes, but in a weird way. You can log T4 Period which would be your second VSS. You can than write a math channel to convert this T4 period to a MPH. So you can view your front wheel T4 vs your rear wheel T3(VSS) to come up with a slip. However it is going to be slightly off only because of tire diameter changes from growth.

Funny to hear the methods of 'calibration'. Lol

There should be simple math to get the calibration number based on number of triggers and tire circumference.

And for what it's worth, two trigger points on my rear wheel has been more than enough resolution for my purpose.

dturbocivic

we use time based. :-)

bingo!

I've done it a few different ways with AEM, Haltech, S300. This is how we set it up in ProEFI. Pretty Simple, no fancy math needed. Nice thing is you can change the input type on the fly, no converter boxes or having to open up then ECU to accommodate your sensor.

u just found those images on google lol

haha, nah made some screen shots of one of my customers Maps..

Boost control = power management

Bugermass

There are other ways to manage power that are a lot more precise than boost control.. You have to remember that not only is controlling power with boost less granular but its also not instantaneous, you have to wait for the turbo to get where you want it. I can show examples if you like..

MR.johnson

What ways do you use.

Bugermass

Currently I use time or speed based launch limiters and retard for power control out of the hole.. For power down the track, with the current system I use most commonly we have differential wheel speed based traction control. This uses ignition timing to precisely control wheel spin all the way down the track.. If you don't have either of these, say with like S300, or older AEM systems, you can use the main ignition maps (obviously within reason) to really fine tune the power delivery from the launch all the way down the track. Using a combination of boost control and ignition strategies you can get very precise control of your power output anywhere on the track.

Basically you can keep the turbo zinging away so that the power is always available, then use ignition to finely control it within your needs.

Not hardly...

Yes!!! ....DBW it's going to be great!
...soon.

Bugermass

lol, funny you mention that, I've considered using the DBW with ProEFI on a race car app. Just havn't had a chance to mess with it yet. Could probably do some really neat stuff with it.
