will this system utilize the stock MAS or can a 3 bar GM MAP sensor be used?

ignore this question. I just realized how dumb it was.

Not as dumb as you could assume. I will be in fact working on a complete solution for running the car off a MAP sensor. I was going to target a 2.5 BAR sensor but there is no reason why you couldn't use a 3 bar instead. The solution requires some firmware changes and those require a lot of testing so it will take some time.

On one side if you purchased the tune I feel it should belong to you and you should be allowed to edit it for your own use as you wish. On the other side I wouldn't want one guy to buy a professional tune and then post it on the internet for everyone to take.

For pricing, it will be less than a standalone option, I can say that for sure. It will definitely cost more than a tune for a honda given the quantity and the investment I have into it.

I guess my question is can I make any changes using your software after I get the tune from them? Say I want to change the idle speed. Would I have to load their entire tune into your system, or could I read and change just that one setting?

Technically it's entirely possible. Ethically, I'm not sure. I need to get the 05 stuff done before crossing that bridge.

I'm all for that. If I decide to slip the bonds of Stock Category, I'm going to want the torquey deal.

Subscribed. Really looking forward to stock ECU tuning and advanced functionality.

Hackish! This is great! This is one thing that we really needed! This is the first car I havnt been able to tune on my own. Cant wait to see the finished product!

Hey Hackish! How's it going? Dont mean to bug you its just I keep getting reminders for this thread and I keep promising myself a Christmas present

That's all really.... Happy 2013 from across the pond.

[hackish]

It's coming along well. I decided to take a bit of time off for Christmas. Will be back at it in the early new year.

This is a complete noob question, but as someone who is thinking of going to a standalone in the future (when upgrading to BOE's Rev400TVS kit, most likely), is there an advantage to using your solution for ECU tuning vs going to an EFI X2 unit?

[evansp60]

Firstly if you plan to pass emissions testing you need the stock ECU in many states. Secondly I doubt anyone has tuned the EFI to the degree that it is as well tuned as the stock ECU. For one I know 99% of the EFI's have cold start issues. It's a much cleaner, simpler solution than swapping out the stock ECU. Why re-invent the wheel when you dont have to?

As evansp says the stock ECU has all the features you'd expect from a factory quality car. It starts and idles happily in all temperatures and retains all the factory diagnostics.

Imagine your car goes into limp mode at the track. All you need is a standard OBD2 diagnostic unit and you will know immediately which fault the ECU detected.

Nearly every mechanic on the planet can tell you where to look if you get a coolant temperature sensor fault code. On a standalone ECU you really need a specialist with the software and specific knowledge of whichever standalone computer you purchased to even diagnose a simple sensor fault.

Provided you have the necessary hardware (cat anyone) I've even passed force fed cars through the local emissions tests. We have the one with the tailpipe probe and they roll it on the dyno and test the emissions gasses.

Thank you all for the education! So is there ANY advantage to using a standalone vs just sticking with the stocker + your software?

[evansp60]

To date standalone has been the only option if you wish to do your own custom tune without having to email updated maps or mailing your ECU. Neither of these options allows for on the fly tuning, they're hit and miss.

Your car might be a little faster with a standalone because your wallet will contain less mass and thus the car will have a better power to weight ratio.

There are some limited cases where a standalone is better. If you needed to control a NOS solenoid or a boost solenoid for a turbo kit.

Nice. I'm sure I speak for many here when I say I'm excited for your solution to come to market. Good luck in all the testing!
