Indeed, you can’t say fairer than that can you. Thanks for the offer James but I think I’ll stick with the 3bar. Nothing has changed really since we discussed the various options the first time – not looking for every last ounce of performance from the map, just a nice upgrade that’s compatible with my clumsy right foot – and on that basis you recommended the 3bar to me. I’m more than happy with the upgrade in performance, its just Rich’s gone the whole hog and now I feel like a sissy!

I may well have to pop back for another chat r.e. the SPS units though, as I said at the time I plumped for the SPS2, I’m unlikely to ‘twiddle’ with the settings on a regular basis but for just a bit more money over the SPS2, you’re totally future proof and can play around with the map a little to tailor it to your own tastes. I know you told me all this at the time I bought the SPS2 but hey, it takes a little while for things to sink in with me!

Of course, if you'd like an independent road test review then that might change things. That reminds me, I must update my first review as the 'throttle off' behaviour has smoothed out loads since first installation.

You're probably right Rich, a few tanks to fully benefit from the Optimax but you get a fair benefit immediately - I scared myself this morning with the way it took off up the road when I 'nipped' out at a T junction.

[EddyH]

For normal remaps yes you need a few tanks for adaption to take place and the ECU to adjust timing itself, this still won't take full advantage of Optimax though. However with Revo and an SPS device simply make sure the optimax has chance to get into the fuel system then tweak the SPS device and the benefit is instant as the timing is alterated straight away.

[DaveH]

That'll be what I felt then!

You big sissy.

Damn.

Hey guys, my personnal view on going for 3 or 4bar specific software is to go for the 4bar software. However my advice to alot of customers is normally to go for 3bar software and then upgrade later to 4bar software, if you're anything like me it doesn't take long to get used to the extra power and want more!

4bar software is definatley the way to go if you're doing other mods to the car; dp, exhaust, uprated I/C, etc. and I'd advise using 98ron with it all the time, in fact I'd advise that for any 1.8t software or not.

If you're interested I posted a thread on the Revo forum regards 3 and 4bar FPR specific programs... I think James pretty much covered it though!...

When people say "98ron" do they mean JUST Optimax or does it include the 97ron BP Ultimate?

That makes a lot of sense to me. TY.

I think the octane rating is pretty critical so I don't think 97ron Ultimate would be a great idea. With higher octane fuel you can run more ignition but too much ignition for a particular fuel = detonation. Having said all that, if detonation were to occur the ECU should back the ignition off fairly rapidly to prevent damage. Clear as mud?

[DGW]

The anti-knock sensors on the engine should prevent detonation. My car was remapped by Jabba for 98RON Optimax but I usually fill up with 97RON BP Ultimate or even 95 RON. I seem to recall that Optimax is well-known for being variable in quality so there is no guarantee that what you fill up with is actually 98RON.

the optimax in ludlow is aweful,we have 1 petrol station and the 95 ron stuff is better than the optimax,i think they need to either clean out there tank or put the proper stuff in

[RevoKev]

Yeah, I did a bit of testing in my own car over a few different tankfulls using optimax, ultimate, and cool blue. Suffice to say cool blue was loads, loads better than any regular fuel but at a cost. I also tried some full on RFT but that was just stupid money. I found that optimax was tending to pull back a couple of degrees more on average than ultimate, however I fill up at larger, regularly replenished Shell stations. If you've got a small unused optimax supply (it can 'go off') then you'd probably find that ultimate is more consistant. Tbh without datalogging facilities, on the road I find there's not a massive amount of difference between ultimate and optimax. Having said that I always use optimax (I've a shell station close to home) unless I'm stuck.
