[Field Marshal Dr. Opti]

£100 off at present. £229 instead of £329.

Tuning box and not a bespoke remap.

Likely to work or snake oil? I tried something similar from Superchips a while back that made absolutely no difference, so I sent it back for a refund.

Which engine parameters are changed with a remap/tuning box?

Well it should double the value of your car M'lud! 

[Doctor Gollum]

With that gearbox? I wouldn't.

The ecu from the Insignificant VXR would potentially offer 320 bhp. Likewise the Vectrum VXR, 280 bhp. If you must...

I'm dubious because the Superchips jobbie sent the car into limp home mode every time I gave it some welly.

[Doctor Gollum]

That's probably because it's trying to protect the gearbox.

Superchips Bluefin it was called.

It just made the car undrivable, so back it went to Superchips.

So £20,000 then.

It fools the ECU into thinking the fuel pressure is lower resulting in a a longer squirt of fuel by the ECU, it probably also adjusts the MAP value down such that the turbo boosts to a higher pressure to get the extra air in (it might fiddle with MAF also, but this is rarely the case) .


Isn't yours an auto?

6 speed ZF auto.

The early 2.8T has a paltry 230 BHP. My car is the later model with 250 BHP.

Still a very under stressed lump though with only 89BHP per litre from a turbo engine.

No real issues with that box, the early ones had cooler issue and the engine coolant got dumped into the box killing it, nothing of massive concern on your era

I'm tempted to 'give it a go'.......I have 30 days to send it back for a refund if it all goes tits up.

It is a good box.

The ZF 8 speed auto on my 5.0 XFR was brilliant dealing with 530 BHP and 550 FT LB of torque with ease.  Being a a torque converter rather than 'double clutch' jobbie I thought the changes would be slow and ponderous.

Nope....more than fast enough, and very smooth also.

[Marks DTM Calib]

There is no better box at the moment than the ZF8, thats why everyone uses it (well, except Merc....)

I have the source code for several variants of the Superchips code for the LC. They claim 500 BHP (up from a standard 377 BHP).

There were minimal changes in any of the maps. What they did was increase the "target boost" levels at WOT from 7-10psi (depending on RPM) up to 15psi. In very rough terms 50 percent more air in is a 50% increase in power out - assuming the injectors can supply sufficient fuel to burn all that extra air.

Given that this isn't a full remap, I'd expect this to be similar.
