Definitely interested. Count me in.
Lotus Emira V6 ECU Tune - Bench Flash

That sounds somewhat hyperbolic, but I guess time will tell.The irony is no one blows more of these motors than Jubu
Certainly, with forced induction, just about anyone can mess around with more boost & fuel, and pull a load of amazing numbers on the dyno, but making them stay together, be durable, and able to do it lap after lap is a whole different ball game.

A couple Qs to figure out how this would go down.
When they sold you one did you have to get any initial programming done to lock it to the car?
Did you ever get that new ECU installed before the lemoning?
If someone bought one from a dealer can they send it directly to you for bench tuning or does it need something first?

JUBU can say what they want, but it has been proven over, and over, and over again that the 2GRFE engine can handle WAY MORE power on stock engine than 460HP.
this has been proven years ago on MR2s.
We proved this on our own Evora running 7400 RPM on the track all summer with a high boost pulley, making over 580HP on race gas.
Many things JUBU says or posts are shown to be wrong if you look at what these engines do OUTSIDE of the lotus community.

We ran our Evora on the track for 6 hours straight banging off 7400 RPM for hours. Zero problems.
Running highest boost (smallest) pulley currently available. The one we specifically had made.
Sorry to say but the "old info" that these lotus guys put out is just that. Old. MR2 guys run stock 2GRs to over 600 horsepower all day.
I believe the current 2GR stock bottom end record is like 850 horsepower.
Example B: JB4. There are V6 Emiras making over 450whp on the JB4. This is equivalent to around 520BHP. Why aren't they exploding left and right?

Yes I bought it at the same dealership that I bought the car from, they had all the info / vin / etc.
no, I didn't even get 300 miles out of the car. Actually it broke before I even got the ECU, I only got the ECU after.
If they buy it from a dealership it can come directly to us.
I'm interested. Someone else asked this, but I assume that the increased redline will not be visible on the tach. Not sure that would be an issue for me but would be good to know. Not having that nasty cutoff would be nice.
We should see if a dealer (maybe Gator) can provide a price on a bulk order of ECU's.

While I have not independently tested I highly doubt the dash will reflect the change in the limiter. It is very likely pre-programmed colors.
It is however dynamic on cold start (reduced redline), and limb mode so there is a chance I'd say.
Why don't you know? Haven't you tested the tune?
no he did not... everthing is referring to a evora gt and nothing to an emira.

Our v6 emira had tons of problems and got lemoned before we could test. We've said this about a dozen times now.

No not yet, we just posted about this service a few days ago.
@VF Tuner
I have asked earlier no reply, if you want to take a risk along with me. Im willing to send you my original ecu this weekend for a flash tune - free of charge - for the community.. ill take a risk that the ecu might not do what it suppose to do, but that risk im willing to take to order a new one in the worst case.
If you are down for this you can contact me to discuss the process.
Win win for both if it works out to be good

Using the JUBU / Syvecs ecu, the redline does shift on the dash to 7200

But does the dash show that the red line has moved? this is what is being discussed.
Sure it will show whatever RPM on the dash but the pre-set red lines won't change to accomodate.
Cool.
I take it then, with your tune @ 500hp+, you'll be giving some sort of warranty against mechanical engine failure resulting from the remap/boost increase?

Yes, the DISPLAYED REDLINE moves from 6800 to 7200 when the Syvecs ecu is installed (assuming you chose the 7200 limit when you order the ecu, as that's an option)
It also has a 5000rpm limit until the wheels are turning (flashes 'LAUNCH' when limiting to this, and the displayed redline sits at 5000), so you can't give a great big rev when stationary like you can with the stock ecu. (stock one requires the clutch to be depressed to give it a really big rev, without clutch depressed, the stock ecu also limits rev a lot lower than 6800, but doesn't show this lower limit on the dash, the engine just doesn't rev)
As soon as you begin to roll, the 5k rpm limit vanishes and off you go.
So basically, you can't redline it and side step the clutch from a standstill. I guess it's a transmission saving feature.
