WORKS comprehensive ECU tune = $449 (minus 10% on pre-orders)

Or, you can buy our axle back exhaust with a mild ECU tune for $379 (including shipping).

Details on the WORKS website.

Sounds good, but it does not exist yet When will these products become available?? Vishnu and other vendors already have stuff to ship.......

 

Is that because its faster and easier to bring a piggyback to market than a reflash?

That said, barring any unforeseen circumstances, we plan to ship our first batch of ECUs to customers who have pre-ordered in the next two weeks.

That's because it's not a chipped ECU. It's a user-programmable computer with considerably more development time and features that our future remapped ECU offerings.

I thought that a remapped ECU would address all sorts of parameters to extract more power from the engine..... Does the XEDE or other piggy-back offer more controls or features than the remapped ECU?

I do understand that the remapped ECU is not user-programmable, but I believe (correct me if I'm wrong) that not all piggy-backs are user-programmable either.... I remember the ill fated Unichip as being non-user programmable......

I believe the SAFC as well as others, including the e-manage are indeed user-programmable which is both, good and bad. Good that you can do very specific tuning, but bad in that you need dyno time and skill to do it... Seems like an appropriately, skillfully remapped ECU would be a good solution......??

 

I think (shiv/Dave correct me If I'm wrong) That these are my only choices because I live at 7100ft. The parameters are different for me and I need a package that compensates for my lower air density AND 91oct gas. Can you guys accurately tune for altitude? Right now I am leaning towards the e-01/e-manage solution (because I can work on boost, fuel AND ignition). For example I can run about 3psi more boost and more timing than you can at sea level to get some HP back. Thoughts?

 

I'm not Shiv, but I would agree with your assessment. There are probably not too many preprogrammed maps that would work ideally for you. I'd guess the e-manage or another fuel/ignition modifier would be best along with dyno time....

 

Chronohunter,

Our maps will work fine on 91 octane, including at high altitude. We would not tune a car so that it is so much on the ragged edge that one of us or our customers couldn't safely take a trip up to your neck of the woods (neck of the mountain? ) and not have the car perform safely and reliably.

The idea with WORKS mapping is to provide a safe, reliable and streetable tune that will work in a variety of area across a wide range of operating parameters.

Ya i think this is many issues with consumers that for me this is my daily driver, so safe, reliable and streetable tuned is what i am looking for. some of these companies are throwing out numbers, that are very eye candy, but the question is are they safe and reliable or am i going to have my car die on the way to work.. Keep up the good work vishnu and works, i can't wait to see what comes out..

 

Some questions for the tuners...

David:
I am pretty new to DSM tuning in general, but not new to pragmatism ( ). David, with all due respect, you have given oodles of vague hyperbole and ZERO numbers or facts to back up your assertions. You answered a complex question with a simple answer. I asked some specific questions and you indirectly approached one of them.

This logic is false. If input is static, any dynamic adaptivity would have to be considered chaotic. I have a solid technical background with grease monkey experience, I would like some hard technical facts. Explain.

Based on Works racing involvement I am very interested in your products. But; again with all due respect; I am growing weary of the vapid ad copy posts. I would like to see some numbers. I am close to making a decision and I would like some hard information. You can call it impatience (as you did in another thread), but lets face it, the 4G63 is not new technology and there are a myriad of products out there that would more than suffice, which you have chosen to denegrate but have given absolutely no proof to support your assertions.

Shiv:
I have signed up for the tuning session here in Portland, but I am having doubts. I am feeling that the bang for the buck is pretty low. I see others using the tried and true methods (lets face it, people have been tuning the 4G63 for a long time and it's limits are pretty well documented) and they are getting better results for less money. If the primary concern is reliability, why couldn't the same reliability be achieved with other piggyback units aside from the XEDE? If I tuned the Apexi S-AFC as conservatively as your fuel mapping that you provide with the XEDE, what exactly would be the difference? Conservative is conservative. If I am achieving the same performance within the same engine parameters with different equipment for 1/2 the price, what is the difference. Can I? If not, why not?

I am not trying to be confrontational to anyone, I genuinely want to know. For all intent and purpose I cannot see that the above questions have been answered.

Sorry for the long post (rant ). A round of ale for all the working stiffs out there trying to make a living.

Driven to drive.

 

bigd,

We will post official dyno charts in the next couple of weeks. In the meantime, please feel free to email or PM with your contact information. I would be happy to discuss our approach to ECU tuning with you in greater detail -- or better yet -- have you speak directly with the lead engineer heading up our ECU tuning program.

-- DavidV

 

No, you cannot. An S-AFC offers no timing control. Instead, the assumed spark timing numbers generated by such an approach is a direct result of fooling the ECU into thinking that load has reduced through MAF attentuation. So, while solving the fuel side of the tuning equation, you are being a slave to the extra, and somewhat uncontrolled, timing advance value generated. Needless to say, this results in compromised performance as far as achieving a good balance between output, knock resistance and most importantly, repeatability in the face of octane limitations most of us face in the real world where 110 octane race gas isn't available at every gas station. You will also find dips and bumps in the torque curve (especially around 5600rpm) where raw timing values are conservative and knock sensor sensitivity is great.

The EXEDE is designed to control timing, boost, fuel and knock sensor sensitivty in a high-resolution 20x20 table with user-definable load and RPM breakpoints. This, by nature, allows you to acheive any results you want to achieve. You are only limited by your allowable octane and the amount of safety margin you feel comfortable with.

S-AFC vs. XEDE isn't a fair comparison. In order to offer the same performance levels, you will need to add on an ITC (ignition control), AVC-R (boost controller) and hire a software developer to integrate future features such as fuel enrichment triggering, spark advance ramp-up rate, data logging, etc,.)

No they are not. They are tuning with perhaps different priorities, on higher-reading dynos with more available octane. That's about as simple as I can put it.

Best Regards,
Shiv

 

Shiv, what about the e-01/e-manage combo, you can do everything you say you need to do with them and the price is again lower. Again as stated we have a lot of respect or your expertise, that's why we are asking!

DavidV, the same tune you use for sea level is not optimized for altitude and running more boost up here (within reason) does not put the car "on the ragged edge" as you stated. That is part of the understanding of MY situation that I was fishing around for...

Thanks Guys

 

HOLY ****... this thread was like reading a book i feel like im back at school all over again.... just my 2cents ... shiv i would love to have your stage zero except for the fact that without u tuning it... it just wouldnt b the same and there is no way in hell im going to cali for just this **** im from northern va

 

Excellent answer. Thanks for taking the time. I too am interested in a hearing how you feel about the XEDE/Greddy Profec E-01+E-manage comparison. Would that be more apples to apples?
