Rica Engineering is claiming a 60 HP boost with their remap, to just under 400HP. Anyone out there remapped with either Rica or another tuner?

Rica makes this claim, which I'm not sure how to interrupt: "100% dealership service compliant". My experience is that any remap automatically voids warranty, so I think they might be attempting to be tricky in their language. That said, every car I've done this with in the past had a mode to switch back to factory settings for services, so not sure it's a big issue either way. 60HP and their claimed curves are pretty damn enticing .

Rica Engineering Chiptuning

 

I don't know how they feel they can make that claim, and it seems ridiculous to me, but I do know that there is no way to hide a tune by flashing it back to OEM. This is true for at least two reasons:

1) Hidden fingerprints--there is a record of ECU reflashes, and

2) If your engine grenades and you flash the ECU back to OEM there will be no record of the events leading up to the engine malfunction--a dead giveaway.

Either or those two are enough grounds for a warranty denial on an engine repair/replacement.

 

You might want to check out the Eurocharged claims as well. The Rica tune is believable since Jag does nothing more than a tune to get the extra 40 horses from the S model. When my F-Type comes in, I'll do both a pulley and a tune to get more torque (that's where the fun factor really is).

 

It would be interesting to get the base model reflashed to S specification and see what effect the different gearing has in a direct comparison.

That torque curve does look interesting though...

 

Agreed. And if you are re-tuning, it is only right that the owner (and the tuner) take full responsibility for an engine meltdown.

 

A smaller pulley might just mean more torque below 2500rpm...

 

Precisely. The pulley is already sitting on my desk. I just need a car to go with it.

 

I think the base V6 shifts too early (even in sport/dynamic mode) and gives up power in the 5-6k RPM band, so I've been interested in an ECU tune.

Unfortunately I was told by Eurocharged that the ECU tune doesn't change the shifting program, it just adjusts the fuel-air mix and does some other stuff.

Can anyone confirm that the gear shifting remains unchanged with ECU tune?

 

I have installed the Rica tune in quite a few of the 340hp V6 Jaguars, both F-Type & XJL. It is quite a noticeable increase in power. The tunes are all detectable as the ECU show non oem calibration. There is no way to take that out by tuning back to stock. I have been told by Rica you don't want to put a pulley on the 3.0 engine.

 

Any idea what their logic is? Their tune alone will only get me another 18 hp and 34 Nm.

 

As with Eurocharged, I assumed they would offer different tunes for each V6, which yields proportionate gains for each car. That chart was for the base car.

When I talked to Eurocharged, they told me on the V8S they needed to flash the OEM software for the R before they could get it to the gains they publish for the R. Likewise, they said they thought they would need to do the same to the base V6 to get it to the gains they claim for the V6S. However, at the time I'd talked to them, they'd never done it, so wouldn't guarantee it would work

I can get my head around why someone might think the pulley change is a little too aggressive.

 

I can as well. But it makes me wonder how reliable the engine is (at 380 hp) if another 40-50 horses from the pulley is going to endanger it. Well...it looks like I may have an expensive paperweight sitting on my desk.
BTW, could somebody measure the diameter of the SC pulley at the top of one of the ridges (in the middle, not at the edge)? That dimension should be close to being the effective diameter of the pulley.(Any V6 model please).

 

Yep, with all the uncertainty and general lack of information on tuning these engines, I'm most definitely staying stock until the end of warranty, if I keep it that long. Unlike you, I don't tend to keep cars more than 3 years because something new and improved always seduces me.

Honestly, even the base car is so tail-happy, I'm not feeling underpowered.

 

According to the specs, your base model is quicker than the S manual, and my tuned/pullied MINI is just as quick. I just wanted to get the torque up a bit from the based model (the torque is virtually the same on the base and S models)

 

As I suspected, Rica posts on their site the same results for the base as it does for the S. 940 Euro for 18 horses (4.7%) and 25 lb-ft isn't very cost effective. Eurocharged doesn't have a problem with putting a pulley on the 3.0L, but I'd like to hear from folks who have done it.
