Lotus ECU Unlocked

Yeah as Pesky says dont get hung up on rolling road figures at all, there are so many variables it is untrue.

It also cant be your map. The map inside your ECU isn’t something that works one day and not the next.

Thanks Rob and Sean - I do know what you mean… my concern is because the guy at Surrey RR said Exige S’s pretty much make 220 on his dyno every time… and mine was less than that… after being more on the Essex dyno… EA did check for fuel issues and compression etc but couldnt find anything… Is there anything else I should check that you guys can recommend ?

I suppose I am suspicious also as so many folks have had issues with the katana kits, which is why I also will look at how turbophils program pans out for piece of mind

Why

Been a little late to post- got busy doing new baby duty :clap:

Couple points. It’s not just a peak power game. I was retuning a “gotham 265” tune last night. The gatham maps are just amazingly off.

The peak power is reasonable. Sure the cam table could use some help, but EVERYTHING “under the curve” is where the big issues are.

-He had an incorrect understanding about the VVTL ignition map. Break points were changed and etc thinking that would make a change but it wouldn’t and didn’t.
-timing in the mid throttle and and mid RPM ranges was WAY off. The car I tuned didn’t just make more peak power, but the mid range and throttle response was night and day smoother and more robust.
-the Gotham tune has no changes to IAT compensations and no changes to knock sensativity tables. This car had logged a lot of false knock. This is all fixable now.
-injector scaler math was wrong ont he gotham tune. the VE table was all shades of goofy to compensate for the wrong math. This incorrect math has impacts that expand into idle, tip-in, transitional issues…
-small cam timing and ignition was basically stock. there’s a ton of room for improvement there!

Again, the car made more power than stock. Even ran better than stock, but there was SO MUCH room to make it better and that’s what this new editor allows us to do…

Turbophil,
Don’t wish to be an arse but can you explain all this in plain English?
I am seriously mystified by all the jargon. There is an underlying assumption that the terms used are understood but for the S1 mob it’s unintelligible. I read with interest the S2 experience but can’t get near understanding without clarity of expression.
What , for example, does “all shades of goofy” mean? :crazy:

Disney’s cartoon version of “50 shades of grey”. :wink:

The Lotus 260 map is great from the factory in my experience …why try to fix summat that ain’t broken ?
There are plenty of aftermarket ecu options for people of that disposition …2 years too late in my view , sorry

Hello,

All shades of goofy means the VE tables didn’t make sense and were done that way to compensate for incorrect injector scaling math among some other incorrect assumptions. It’s hard to get too technical about it without posting images of the maps up for all to see, and that doesn’t seem like the right way to approach this…especially when most won’t know how to read the maps… I have learned that tune was an earlier Gotham tune.

I just had another car on the rollers this weekend that had a newer version of Gotham from the current retailer. It was essentially a Cup 240 tune. I haven’t compared the whole map, but it looks near identical at a quick glance.

As for the Cup260 map. That map is just OK-- and only if your setup is idential to the 260. There’s a lot of improvement to be found in the midrang and on the small cam, moving the cam shift point, spark advance, and getting the AFRs more properly dialed in— of course, if anything on the setup is changed, ie headers, intake, IC, pulley, etc then the cup260 tune just starts to run worse in the middle of the band even if it’s peak power numbers seem OK.

As they say, you don’t know what you don’t know. If you didn’t know that your car could run so much better, you would not know you could improve it…

Given that most of the aftermarket tunes, up until now, are basically cup240/260 based tunes, it seems there is a good reason for folks to consider an upgrade in flash or to buy the program and have their tune tweaked by good tuner local. I agree, the product is a bit late! It would have been great if it were available in 2005, when the Toyota cars were first hitting the street! :smiley:

have you made any progress selling this to tuners in the UK?

Yes.

We’re setting up Daniel Rowbottom at this time. I anticipate he’ll be up and running within a couple weeks.

Well, that’s cleared up “goofy” then. :clap:

did he have an STD? Pluto likes dogging, so i would blame him
:wink:

Yest

This thread has gone quiet, any update yet ? :unamused:

Speak to EA they can do it as well :wink:

How much!!!

£150 buys you a license to remap the GTR ecu with all the features of ecutek.

An extra £300 and a seriously competent tuner with all the tools will map it for you. £1200 for the ability to get in to the stock ecu is a joke. I’d far prefer a syvecs at that price.

indeed

There’s about six cars in LCUK now running the Eliseparts one, I need to talk Geary into doing a bit of a promo price on it, I think it would be good value at around £1200 ish, it’s totally reversible and there are adapters now for cable throttle cars. This or Syvecs are going to have a lot more to offer than an opened up T4E.

The software for the EP one is free as well so it’s easily supportable by anyone.

yeah like options to run alpha-n for ITBs etc
