What is the total cost for this tuning software provided I have no accessport at the moment.

 

Thanks,

Chris

If buying a new AP, it will be about $645 + $195. Well worth the $$$, and if you p/u a used AP, then you could shave off another $50-75 or so....

So you are scaled up to 3.4 and that only covers up to 4.9V? So 3.5 is the limit for the stock maf?

With a VF34 I was already seeing load of about 3.19. Im just trying to cover all of my bases.

What about the tracing function? IS there a way for it to mark the cells?

You can scale for whatever you want. Whether your engine can generate enough load to hit those points is another thing.... If I want I can map for above what the stock MAF reads/calculates, you would just use your wideband and tune your last load column to what you want to see....

I could just as easily have my intake calibrated to hit loads of 4.5, but then my fuel tables wouldn't be anywhere near resembling what's being read by the wideband. Point is, load is a calculated number, you can manipulate it. MAF volts, OTOH, cannot. (Only if you change the size/diameter of it.)

So, I would think with a vf34, you aren't even close to approaching 4.9v, let alone 5.0v. You should be fine with just scaling for the loads you currently see. IF you go bigger turbo, it'll need a new tune anyway....

Currently, I rescaled my fuel/timing maps up to 3.25. However, I am thinking I may need to go up to 3.5.

 

At what point does our MAF run out?

 

While using the map tracing function, is there a way to have it mark the cells where it has been?

Wow, what turbo are you running? The stock MAF reads to 5volts. Although the accuracy at 4.9v on up is starting to push the sensor limits...

I've got an Avo450, and it pushes 4.92v, so I'm almost maxxing it out myself:icon_mrgr .

Edit: Correction, I was just out logging/adjusting wg duty air temp compensation and I pulled a solid 4.96v from 6.7K up.. !

^^Yes, I have! I basically looked at the existing breakpoints, and then used interpolation to allow me 3(?, I forget, but I have up to 3.4 now) new load columns.

I left the 1.4 and lower load sites alone, and then afterwards, I increased by .2-.3. It took a little time using a few WOT datalogs and then using an excel function that interpolates between cells, so that I had a good idea of what my changes impact. And also to match up to what my previous logs had.

I rescaled the Primary Fuel, Ignition, and Dynamic Advance with the same breakpoints. They don't need to be, but I figured it would be neater. I'm also thinking of moving some of my current breakpoints around a bit, now that I have pretty muched seen where my alky map is riding...

What you propose is fine, the biggest thing is to just pick columns that have a pretty linear change, those coould easily be cut out, and slid over, opening up more resolution for where you need/want it.

spotted Edmundu in pompton lakes today.. about 45-60 minutes ago... you flashed an waved.. i flashed back.. i was at the traffic light next to a silver bug-eye... jus letting you know that was me lol, we've talked at meets before... first time ever seein you on local roads..

Yeah, I spotted you as well! On my way home from work....

I don't see that it would really benefit that much. I changed mine in driveway. Broke 3/8" knuckle, but besides that it wasn't too awfully bad. The one on driver's side closest to firewall was the hardest. Have to work it a bit to get out, then same to get back in. I rolled it upside down and worked it out that way.

It would have helped me taking it apart multiple times to chase down what turned out to be a bad coil... My back was sore the next morning, from being bent over, and r&r the battery a few times too!

I wouldn't pay for use of a lift, but if one was available, as always, it does make it a little easier.

would this be any easier from under the car? ie if it were on a lift

Well Yes it would, because the car would be able to be lifted so that you need not bend over so much. But you would still be accessing them from up top.

Ted - where can you get teh mu data? I checked Hawk and Cobb for mine and got nada.

Hawk tends to be very stingy with their technical data, don't know about Cobb. I have Ferodo's(ds2500), and they do give out their specs: 0.5 mu across their MOT up to 1000.
