To you peeps who had had a full remap done (not tuning box), how is it?

Which one did you get, is it worth it.

What sort of 0 to 60 times am I looking at?

I'm sorely tempted and have string theory garage on my doorstep.
 
Ive had mine done! Made a video ill link below!

I personally love it! Ive been driving the family a lot this week and noticed even more that on part throttle and low boost it drives just like OEM and like a normal car.

But geez once in boost it flies and pulls nice and hard now. Ive not 0-60 timed mine yet as ive not got equipment to do it accurately and know if I do it on my phone the comments will be full of "numbers aren't accurate" comments.

 
Given the newness of the engine, if I decide to remap I will use Litchfield because of their warranty coverage option.
 
I never knew the ECU had been cracked!! I’m curious what happens with owners down the line if returned to standard will they lose warranty can it be proven?

Might make prices stronger for these

The reflash just shows as a software update. You could in theory flash back to stock and it would look like any other software flash at the dealer but if your engine grenaded itself and you sent it to Toyota with a freshly flashed ECU with no sensor data it'd look highly suspicious.

I've had mine remapped by a local company. Intake, exhaust, intercooler, BOV, valve springs, downpipe and GPF removed and it made 290whp and 375NM at the hubs which i'm delighted with - seen OEM hub figures around 220whp so that's a gain of around 70hp over stock. For comparison's sake I had the TDI tuning box and did some runs with it fitted and disconnected - bolt-on mods with the OEM ECU managed 261whp and with the tuning box on it made 270whp. The tuning box makes more gains on a stock car because it seems to overcome restrictions at the expense of EGT's, remove those restrictions and the gains are less noticeable as more power is naturally freed up by the mods without needing mapped.

**also wanted to add the torque spread is similar to what Tino saw, especially around 3-4krpm there were gains of 40NM over the tuning box which is really noticeable in terms of driveability

Very nice! Your making me want to do it but I need to find my balls. Just paranoid if lost warranty and value of car plummets
 
I don't think the engine will blow up as long as you use 97ron+ and be sensible with warm ups and cool downs.

There are plenty of owners with tuning boxes with no issues and arguably these are worse than a full remap.

But yep agree it's always risky with this sort of thing.
 
Well just to offer a balanced perspective I had a low oil pressure warning come up the day after I left the garage and it’s just cost me £370 to replace what was diagnosed as a faulty sensor.

Probably just bad luck but gremlins do exist. For every Motive Garage pushing 500whp with minimal issues there’ll be an unlucky car with endless faults. All part of the fun I guess

Yeah, the documented sample of 1 under limited time is quite... well limited.

Also in modern times not everyone is open with issues, scaling from 'forgetting to mention small stuff' to full on hush hush - outwardly on social media all is great and cool, while in the often closely controlled closed owner groups, peeps may be running from one problem to the next in a seemingly endless stream...

Where not necessarily getting all the data, botched up jobs usually no point in showing off...

You raise an incredibly pertinent point.

With automotive tuning, one should never assume the readily available information (or lack of) about tuning a vehicle stands for anything.

This is a new engine, pushed hard enough to perform to a level without compromising it's day to day performance with the attached ancillaries, whilst making it reliable enough to comply with Toyota warranty targets.

Anyone tuning these is learning how to crack ECU's, understanding the quirks of it's ability to consume air, fuel itself and deliver it's power. Toyota have had a raft of Gazoo's finest inputting into this engine for months, so anyone expecting to bolt on a few bits of carbon tat and see transformation are possibly being optimistic. Given Toyota have had to comply with EU regs for emissions of course there will be some scope, but it will be tougher to unlock than in a bog standard 4 cylinder mass market engines built for shopping trolleys.

Then there is the darker side of tuning, the ones that don't get published when the limits are nudged just that bit too far. Any modification is pushing limits to new levels, and like anything you make a change here, and there will be a knock on impact somewhere else. With a new engine platform it's a journey into the unknown, especially if different principles of design have been employed. It might not be immediately apparent issues either (esp. if it's drives a failure of things like pistons or bearings), but these are often the kinds of issue that fly under the radar as they're bad for business. I've tuned my cars all my life, so I'm not saying people shouldn't tune cars, for enthusiasts it's a way of life, but they should have their eyes wide open, do the research, be prepared for the worst, and adhere closely to servicing / warm up / cool down routines.

But NEVER ever think because you haven't heard of many issues there haven't been any, some are just waiting in the side lines!

Ok I should update this as things move quickly. So the oil pressure sensor is apparently a common issue when tuning these, the thought is that because it's a part originally for a 4cyl car the harmonics of a 3cyl engine are shaking them to bits. Fensport have had a few failures, mine failed and a guy who lives near me had a faulty one too so it sounds like it'll be a common fault in furture. Counts as a warranty replacement though so 3 hours labour and a replacement sensor, not too stressful. It's a dual temp/pressure sensor and when it fails it reads fine when cold but when warm the pressure reading drops below 1bar and triggers the fault code.

As for the map.. my car made good power for about five miles and then developed the oil pressure fault and had a heavy misfire. The misfire got progressively worse, the garage was looking at coil packs, plugs etc and was getting nowhere so I took matters into my own hands and had it trailered to Fensport who had it fixed in half an hour - looks like when they did the valve springs they disconnected the earth for the coil packs at the back of the engine and never tightened it up again properly. Weeks of no car and a 300 mile transport to find out it was a loose bolt, it's hilarious but scary at the same time.

My car's now on a Syvecs, not putting their map back on the car given the horrors that have been found with regards to their work. More to the story than this but yeah, if you're doing it go somewhere reputable where you at least stand a chance of being looked after!

Do you have the cherry blossom car? Think I saw your post on FB about it. Glad you've gotten it sorted

No doubt it absolutely sucks that you've had a bad run of luck there and the car has been out of action for a while, to be clear about the above is it fair to say that bad luck aside, your issue isn't the tuning but how you've been handled by the tuner?

Correct. I’m waiting for all the findings from Fensport to see what state they left the car in but the quality of their work elsewhere has made me question their abilities.

The car only did 5 miles or so fully mapped and developed a misfire that progressively got worst so I never really got a proper chance to rest the map. With no confidence i didn’t want to run it any longer either. As far as I know the map may well have been ok but it was flashed back to stock before being sent down South so noone outside of them has had a look at it

Yep that's me. Thankfully the issue wasn't anything terminal but it was such a fundamental error I do wonder what else has gone or could go wrong, Fensport had it for half an hour and it was running. The garage hadn't tightened the coilpack earth at the back of the engine after doing the valve springs :ROFLMAO:

Not naming names at this point as they've found a couple of other red flags regarding the work done so they're doing me an oil change and an overall healthcheck before mapping the Syvecs and letting me come pick it up. Making the most of them having the car as I have complete confidence they won't leave me with a dog of a car.
 
Fensport logos being incorporated into the next livery? :)
 
I didn't even know they did repairs, I thought they only sold bits.

So it wasn't the remap that broke your car it was the garage that did some work. That is good to know.
