Received my ECU today (thanks Kevin!) and installed it tonight.

Could only drive it a couple of blocks in residential streets, will know more tomorrow after I take it to work.

Although it seemed torquier / less low-end hesitation.

Anyone else driven theirs yet?

Separate question: when I take it for service do I need to tell them to not install any updates of any kind as it will overwrite this programming?

Or are things more modular in ECU's and one could, for example, update the CC software without impacting what Eurotek did?

I'm in exactly the same situation as you. Just a quick drive around the block, with redlines in first and second. Hopefully, I'll be able to do the mandatory (yes, officer, this aggressive driving was required by my mechanic!!!) driving. Hopefully it won't rain enough to make it dicey.
It felt strong, but then I've been driving our Lexus SUV for nearly a week, so it's hard to really tell any improvement.
I'm also interested in the question about 'protecting' our Eurotek programming.

:lol:
ditto on the above. I didn't see the instructions which were attached via the "packing slip" so I didn't drive it as hard as I maybe should have around the block. Nonetheless, seemed to have much less hesitation at takeoff and smoother acceleration. I can't wait to drive it more briskly tomorrow. I also would like to hear about "protecting" the programming. Also it stated on the directions that if the battery cuts out to repeat the steps....does that mean if the battery is disconnected it resets the learning process that is supposed to happen?

Just got back from a short 25 miles test run on I-10. Never had the chance to red line it in 6th gear (i wouldn't dare anyway). The fastest I went was between 130 and 135 in 5th gear near 6500rpm. Almost red lined but had to step on breaks when I saw a highway patrol sitting on the shoulder before I-405 junction (luckily Eurotek made my car invisible as well...hehe...he didn't see me).

max power: before-335.7 @84.0F after-TBD
max torque: before-282.8 @84.0F after-TBD
top speed: before-180mph after-TBD some time next week
mid-range torque: increased, the car takes off at around 3300
throttle response: superb, doesn't drag
gear change: still rough between 6.5-8K rpm but smooth under 5K.
ignition timing: did not shake at high rev and speed (more psychological than factual)
tubi: dampened at start and lower revs but gets louder at around 4K which originally had almost no sound when in 5th and 6th gear.
fuel consumption: a true gas guzzler

Ok, drove it some more...

Very noticeable changes, feels like the engine has been "unrestrained" and my GS is much more responsive, way more aggresive.

The strange delay from a full stop is gone as well.

A more raw, better driving experience, no doubt - this is more in line with what I expected from a Ferrari engine.

On the down side it seems more hesitant do downshift from 2nd to 1st, which results in more lagging while in traffic. Not a big issue. And it seems like it was running a couple of degrees hotter but hard to say at this stage, could have just been the way I drove this am.

So far thrilled with this change!

I couldn't even got to redline on 4th, maybe over the weekend...

Are you planning on putting yours on a Dyno again? Eager to see those results!

some time next week.

It's definitely running hotter. The "slow down" indicator went off once last night.

A more raw, better driving experience, no doubt - this is more in line with what I expected from a Ferrari engine.

fun fun fun!!!

Track day, anyone?!!

by this I thought that you were going to go out to a desolated area and achieve the top speed yourself...

Glad you guys like them, Phil is very happy also. Couple things he wanted me to tell you guys.

RQ- The reason for the slower downshift has to do with the 91 oct. If you can get ahold of some 93, that should solve the problem. Albeit it may not be worth it.

wannabeitalian- It won't reset the ECU no if that's what your asking.

Reminder to everyone once you take the car in to the dealer and they need to make any updates make sure they don't update the engine ECU. If they reflash it, it will be returned back to normal. Now the dealer will rarely ever do this unless you have a major problem and as far as the majority of these updates go, if there are no problems with your car, don't bother with the updates.

Thanks Kevin.

Although here is Florida I'm using 93, not 91 (at least that is what Shell says).

I thought maybe the slower 2nd to 1st shift was on purpose because of the different torque curve.

Can you see if Phil has any other thoughts on this?

Sorry got you confused with the other Gransport guy in California. I'll ask Phil first thing tommorow morning. It may be because of the torque curve not sure. Is it at a certain RPM or all throughout from low rpm's to high?

Well, it pretty much just won't go into 1'st until almost a complete stop. Just different than how it used to be.

Lingering in 2'nd can be a bit of a pain in heavy traffic.

But not making a big deal out of it, easy enough to get into the habit of manually downshifting.

Still, curious to hear if Phil has something to say about it.

Thanks!

RQ-

Q. Is the automatic downshift from 2nd to 1st affected by the upgrade? If so, is there a way to avoid this?

A. No its your driving style. Give it time you an the car will adjust, you may notice the car will REV in between shifts to optimize power transfer, OEM the cars RPM will drop in between shifts, = lurch effect.

hehehee... if you are interested we could try it on 118 this weekend... :twisted:

wait... "Sorry got you confused with the other Gransport guy in California"

ECU experience

I just got my ECU back. I can't stress enough how much I'm satisfied with this upgrade. It seems like I'm driving a totally different car. I can definitely feel the added torque. I feel like my car is unrestrained. The thing is, I'm burning more tires than ever.

For those questions concerning how to determine if your dealer had 'overwritten' your ECU programming, the answer is very simple - You can absolutely tell the difference.

I'm almost complete with my upgrades: 19" wheels, Car lowered, Tubi Installed, ECU upgraded, and Chrome badges.
I'll wait for the warranty to expire before I install a BMC Air filter.

Thanks to Kevin and Phil. You got one very satisfied customer here.

Dennis,

Thanks for the kind words and feedback! I'm glad you like the upgrade as many others have.

Manual transmission Eurotek

I don't know how important it is to perform the "aggressive driving" (recommended by Eurotek) on the GT, but I am doing my best. I will echo others who feel a definite performance improvement. Torque after 3000 rpm seems to be the biggest difference. I broke the tires loose in 3rd gear just accelerating in traffic (traction control kicked in). This is completely different compared to the torque prior to the chip reprogramming. I also felt that the rev limiter did not kick in when I accidentally exceeded the redline, but I tried not to repeat that effort.

Nothing but good things to say about the upgrade.

Phil raised the RPM limit for my ECU, maybe it was done by default for everyone? (your invoice should show that)

MVP

· #19 · Dec 5, 2005

The RPM limit was raised for everyone unless specified otherwise which nobody did.

iufan- Glad you like it!

MikeA

· #20 · Dec 6, 2005

What was the rpm limit raised to?

I also feel improved acceleration at higher rpm's. The car definitely feels stronger. I hope to get it dyno'd this coming week and I'll post the results.
