VXR injectors for 2.4T5

**expolicev70t5** · Thursday 18th December 2014, 17:09

Reason I was looking at Greens or VXR's was because I was considering one of John's (Dream3r's) maps and he states you need these injectors to run with it. Originally I was going to run with an MTE map and this would not need the uprated injectors but after reading about over boost I'm little dubious about MTE now.

People with the old P1's chuck in blues, for example, without mapping for them without issues, and that has a far less sophisticated ECU than a P2.

The 2.4 t5 map is written for vxr injectors / john compensates from speaking with Shem, as shem is mapping mine once all p1 projects are finished

No, I know that. I was just questioning what James said as he was referring to changing the injectors without remapping the ecu. I know that changing from greens to VXR's on my S60 caused no problems without alterations to the map.

Baiscally, from what the remap specialist told me, he said that the injectors need to be 'told' to squirt the fuel out for set period of time to avoid over or under fueling.

On a foot note, he said that he can set engine timing to accommodate 95 RON fuel but you'd loose a few horses. However, having the engine set to run on Super Unleaded and then using 95 RON will cost the driver even more lost horses. The ECU will adapt and run with less power quicker than it adapts the other way of relearning it's 'potential' when refilled with 98 or 99 RON again. I had an interesting chat with him.

So who's the "remap specialist" then? Interesting to know other companies/people who are/will tune Volvos.

Ask for Stef or Andy...........

They also prep cars for Motorsport and offer full engine rebuilds, upgrades etc.

On a foot note, I can't get my head around why anyone would want to run regular unleaded fuel. The only reason is because it is cheaper. If someone really needs to save 3 or 4 quid on the price of a tank of fuel, then you shouldn't be running a powerful 250+bhp car capable of 150+mph. If your a cheap ass on fuel, what else are you scrimping on?! Just don't get it.

Some people (not me), just do it for the Clubcard points.

I did drive from the southern with blues in, whilst Martin had my greens for a refurb (which he sent on a few days later) the car was not a happy chap lol. Wasn't such an issue as nicci was on half term.

Mine certainly doesn't like cheap fuel, I get ghost codes and 17mpg compared with 22 on nitro plus and no issues. Plus cheap Lego toys for Evie.

Tescos do 99 you know!

**JamesT5** · Thursday 18th December 2014, 18:57

95 or 98/99 RON seems to make little difference on my T5 at the moment because apparently it's "like a sieve" according to the guy who did the smoke test for me, plus it's running a factory standard map. The handbook says that the car will run on Unleaded (91 RON) but Premium Unleaded (95 RON as we know it) is preferred.

To be honest, I can't think of anywhere that sells 91 RON unless you fancy a trip to Poland out in Europe somewhere.

Yeah but I've heard it's not as good as Shell V-Power Nitro+.

**JamesT5** · Thursday 18th December 2014, 18:58

Apparently, the remap guy told me that Octane Boosters are a waste of money because they don't work.

What nitro plus 102? It used to say on the pumps but doesn't now

V-Power Nitro+ is 99 RON.

**JamesT5** · Thursday 18th December 2014, 19:22

V-Power Nitro+ replaced Optimax iirc, which was 98 RON; the same as BP Ultimate and possible Total Excellium).

I use 95.................don't really see the point in using super unleaded for my car

**theflyingbrick** · Saturday 20th December 2014, 17:48

I just sold a set of blues for 50 quid posted!! I now have a set of greens that I would be willing to sell but I need to get bigger replacements first if your interested?
