How much serious interest is there in a complete ECU replacement?

I have a source that said they would consider it if there was a huge demand for it.

So report here if you are honestly interested in getting one if the results and price are fair.

Once I get a list, i'll send them a reply and see what they think.

The company is reputable with Subaru's and wanted to stick to Subaru's, but like I said, if there is a huge demand, they would seriously consider it.

zillinois (2003 6MT, $800-1,200 , depending on functionality)
kpiskin (2003 Touring 5AT, $400-500, want ECU automatically adjust to mods as they come (eg. plenum, pop charger, cats, exhaust etc.) without slowly losing power and requiring a reset of the ECU. I don't need any real level of control, but would want to take advantage of non-FI mods.)
Z BOY (2003 Performance, 6MT, $500-2,000 , at least 2 maps: 1 for daily driving, 1 for WOT/350CHP, ASAFP)
ZU L8R (2003 Touring/5AT/$800-$1,000)
nizmoz
subdriver [350ZMotoring] (year?, transmission?, price frame?, concerns are the same as kpiskins')



Does this look good so far?
Updated.

syf0n (2003 6MT, $600-1200 , I'm very interested in this if, as you stated, it does a better job than what is already out there and doesn't qualify as highway robbery in the payment department. There are a lot of variables in regards to cost since the end product may or may not have a number of features, hence my price range being so broad. I am speaking of things like laptop compatibility/tunability, etc.)

Come on guys, I know some of you might have some questions/comments, let's hear 'em.

If it was programmable, user friendly and actually works there'd be a ton of demand for it.

I think that the ECU is electronically linked to the keys though. I don't know if there is a practical way to overcome that problem.

You can put me on the interest list though.

Help me out here, what is the difference between TS' re-flash, and this "complete ECU replacement?" Plugging in a computer into this device is identical to the Unichip or Greddy for example. That is, this is the same methodology. None of these devices will produce more than 10hp at redline, period. These devices are best designed for F/I or where air/fuel mixtures have been affected by significant engine modifications. However, the G35 does not responds to these “piggy-back” or “replacement” produces. That is, some vehicles do exhibit a bit more performance but the G35 does not. As well, any perceived performance will be at redline. None of these devices “make” the vehicle faster. They simply allow slight modifications in the air/fuel mixtures via maps as well as provide secondary “tweaking” such as bumping up the rev limiter, etc. However, the vehicle will not create horsepower or torque. These produces simply modify or reorder the fixed performance parameters of the engine by means of map manipulation. Further, there is the issue of closed-loop. As aggressive as the air/fuel maps are, the engine will pull back timing anyway. At any rate, this product will never see the light of day if it is a penny over five hundred.

This is a standalone, not a piggyback or ECU reflash. The disadvantages to the current standalones are you lose important (to daily drivers) features (such as TCS/VDC/cruise control).

Now, some of these people expecting this product to be under $1,000 are severly mistaken, because NONE of the standalones offered even go under $2,000. I think I can talk them into a $1,000-3,000 group buy price (later on, once it's been completed).

They will probably copy the codes for certain things like that.

Mark me down as "interested". I've been following the ECU summary thread by Sentry on my350z.com's FI forum and I'm almost settled on just going the Vortec route on stock internals and being happy with 350-375rwhp.

HOWEVER... The idea of staying NA is appealing to me and I am very interested in seeing what develops. The true "magic" will be to see what Nissan left on the table when making our ECU. Just because you can control the 3 'big variables' doesn't necessarily mean that you can make more power safely. I wouldn't want to sign up to spend $1000-$2000 and find out there is a whoppin' 6-8rwhp extra (on top of cams, headers, plenum, cats, exhaust, etc...). Now throw out 20 more rwhp and all of a sudden you've got a lot more interested people.

A few questions... who would be able to "tune" this ECU for us? How close would they be to Orlando, FL? That's another big problem. Unichip doesn't even have an authorized 'tuner' in Florida, neither does TS. That leaves a guy like me looking at staying with stock internals due to not being able to get the system tuned, which pushes me into a Vortec or staying NA... oh the dilemma...

I'm not sure how that will work. Unichip and HKS don't even have an authorized tuner in the southesat.

last i hear AEM was working on a "standalone" of sorts for the VQ. The EMS will plug into the ecu via a harness, so technically it wont be a full standalone, but it will have full standalone capabilities like all of their EMS'

it probably wont be out for a long time though

I'm not interested in what AEM is doing, but if others are interested, someone called the other day and it's still "put-off."(and I don't see it coming this year or even next year at this rate)

Thanks, haven't posted much here since I don't have a G35 but maybe i'll stick around more for the performance section.

Guys, if I don't get a response from the company on Monday, i'm going to have to call this thing off. I'm not sure if they weren't serious (even though they said they were) or if the customer rep. is trying to ask the owner of the company sometime. I have no idea, but I do know that they haven't replied after the first reply.

If anyone wants to take over this thing PM me and i'll tell you the company and give you the website.

Wait until Tuesday before you do that though.
