Once you have done your initial scan of your ECU you will need to choose the appropriate map from the list of options to load on to your ECU. The OFT wont automatically choose the right one for you as it has no way of knowing what you have done to your car.

So the OFT gives you a list of tune files based on ECU CalID (not any kind of smart detection of stock/after-market add-ons), got it.

So then it's still a matter of trial-n-error to pick a tune file closest to your actual config, load it onto the ECU and test, then choose another that's close to your config, load THAT onto the ECR and test again...Repeat as necessary until you find the one that works best for you. Is that right?

Sortof. It shouldn't be trial and error at all. The "stages" are pretty well defined by Shiv. There are different versions of the stage 2 maps based on if you have EL or UEL headers.

OTS Map Requirements:

Stage 1- For vehicles equipped with original header. Other exhaust modifications also compatible. Stock airbox (with or without aftermarket drop-in panel filter) also recommend. Premium grade fuel only.

Stage 2- For vehicles equipped with aftermarket cat-less headers. Other exhaust modifications also compatible. Stock airbox (with or without aftermarket drop-in panel filter) also recommend. Premium grade fuel only.

Stage 1 tunes are for essentially stock vehicles with maybe a high flow panel filter.

Stage 2 are for vehicles with catless headers and there are UEL and EL map versions.

Stage 2 E85 tunes are for vehicles with catless headers and those running E85 ONLY and there are UEL and EL map versions.

Cat back exhausts/overpipes/front pipes dont really matter for the purposes of choosing maps.

The only exception to this rule is if you have a stock vehicle and plan on running E85 fuel, the Stage 2 E85 EL map has been tested as safe for stock vehicles. Just remember that you can ONLY run E85 with the E85 maps. If you need/want to swap back to 91 or 93 octane then you'll have to flash back to a non-E85 map.

All of this gets slightly more complicated once Shiv releases the v2.0 maps. Then there will also be 91 octane and 93 octane versions of each map.

So essentially you'll pick the one that matches your car and load that to your ECU and that's it.


EDIT:Just saw that you have Crawford BPB's. You'll have to download the beta map off http://openflashtablet.com/products/...ads/index.html for the BPB's and manually load up the map for that onto your OFT. Make sure you load the correct CalID and choose the correct fuel map. Then you'll flash that to your ECU.

Is the OFT any different than how the COBB AP works? I loved the hell out of my AP.

Never had a Cobb AP but looking at their web site

Probably pretty close, maybe missing a couple of features and screen not as hi res, but basicly same idea and same basic functionality

suggest you look at www.openflashtablet.com

Conceptually, the are the same. That is, a handheld device that doesn't require a laptop to flash your ECU and that can be uninstalled and then re-sold if needed. The differences boil down to details such as:

OFT provides unencrypted ROM format vs encrypted AP
OFT provides mode data display options (more channels simultaneously)
OFT is touchscreen vs AP buttons

If you like the AP, you will like the OFT

Cheers,
Shiv

+1000 on the unencrypted ROM's

anyhow back to work on V2.0 and stop posting

Does the stage 1 map for stock vehicles increase the hp or torque at all? If so by how much?

i will be getting my oft today or tomorrow. from what i have heard from @shiv is i can run the stage 2 el since i have full exhast and intake bolt ons. i will run this map and watch to make sure everything is in line. once i recieve my headers i will be running the stage 2 uel map then switching to e85. cant wait

Untill you get your headers installed run the Stage 1 maps for Petrol

You can run Stage 2 E85 EL map with stock headers but only on E85

When you get headers you can run stage 2 petrol maps (EL oe UEL depending on headers)

He said Shiv said it would be fine ??

Not sure where he got that information but unless something has changed that I've missed, unless you are running E85 then the Stage 2 maps are strictly for cars with catless headers.

This isn't the first time I've seen people ask about running the stage 2 maps on cars with stock headers. Not sure why they would want to do so. The stage 1 maps offer a pretty nice bump in power and running stage 2 maps with stock headers and 91/93 octane doesn't sound like a smart idea to me. Then again, I've always erred on the side of caution. Personally I'd run the maps like they were intended to be ran and if I wanted more power I'd just buy what was recommended to run the more aggressively tuned maps. You're not going to get the claimed power output of the Stage 2 maps with that stock cat in place, so why risk it?

If you have hi-flow main cat (front pipe) and stock headers its a bit of a toss up between stage1 and 2 maps , yes you could probably get away with stage 2 but probably safer on stage 1 map as it runs less timing advance than stg2 designed for catless headers. (Stage 1 also runns a bit less fuel up top as well, OL fuel table is a bit leaner))

But you would want to look for knock and check AFR at higher rpm if you want to try the stage 2 map with stock headers and hi flow cat. The remainder of the exhaust makes little difference to tuning

[raven1231]

I agree with the both of you, just figured Shiv would know better than all of us is all. I would recommend running the stage 1 map as well, no point in risking detonation for a potential few hp difference.
