Just thinking about an ECU remap

[rashg60]

Nice! I'm booked in on the 27th. Excited isn't the word!

I had to wait 5 weeks for mine so know exactly how you feel!

so all worked out well whats next ?

is the K & N Panel filter ?

did you do the pre dat delete ?

did you go for the 5 maps or just one

get the graph up
what do u think 0-60 times are now and top end after remap

enjoy and well done nik and r-tech boys

K&N panel filter - I'm not convinced by the cold air inductions kits!

Not done any other mods except the above.

Just had the one map in the end.

It feels like the 6 second mark for the 0-60 times but haven't actually tested it. I'm too busy enjoying the drive at the moment with a massive smile on my face every time.

I'm still unsure on how to add attachments/pictures to this thread, hence haven't been able to share the graphs just yet.

When you guys say 'pre cat delete' does this mean removing the first cat altogether?

the first cat the small one has the white chalky stuff inside just need to smash it out

and then the car breaths better and exhaust will sound better and also 3-5 bhp more

so win win

I'm not sure I like the sound of 'smashing' the exhaust.....sounds rather primitive. Or is this the norm and what everyone else has done?

It's not what everybody has done.

Interesting that 83% would buy a standard car and some of that number would then proceed to tackle their tuning with inadequate budgets and DIY where sometimes neither the tools or the ability exist. Under these circumstances I would buy standard without a doubt. Even then you may look for the stamps in the book and think to yourself 'Oh great, FVWSH and standard' but you could be very wrong. How many return to standard sales do we see here?

It's entirely conceivable that somebody could modify (in some cases the term ameliorate is more accurate) their car and spend as much as the cost of the car again in doing so. If this is done with with new OE or better parts, advice from a respected tuner who has experience is adhered to, no cheap short cuts taken, and vehicle unique parts (ED30 or Pirelli) are retained why would you not want to buy this car?? Some are modified for show, others at an engineering level with an objective in mind. Show 'vs' track for example.

Here's an example, LSD. Circa £1400 fitted and none of it's coming back to you. Does it make a difference? YES, unequivocally . Next to stage 1 map it's the next best thing you can do for these cars (unless the 'scene' is your thing in which case you'd probably spend the same on wheels or 'bagging'). If you want to remove mods later to sell and getting big numbers is all you're interested in then this is not for you.

My point here is that not all 'modified' vehicles are the same. Some are highly desirable, others may be interesting for some to look at but drive terribly, or not.

Most of the respected tuners can keep you entertained with anecdotes regarding vehicles coming in with bodged partly finished works or owners with no mechanical empathy or appreciation wanting high levels of tune applied to a vehicle that hasn't been properly cared for. Some will actually decline to work on vehicles where this applies unless the issues are corrected.

They can also tell you about remarkable vehicles that have had the right money spent and the right parts bought.

There will be awful modified and standard vehicles and also exceptional modified and standard alike.

Thanks for sharing your thoughts flashp - very interesting.

We all think that our choice of mods are the best, regardless of how we choose to have them fitted (either professionally or cheaply). I'm always hesitant when buying a car if it has been modified - the boy racer label does not disappear so easily and you always assume the car has been thrashed/abused. I suspect many of the people that have voted believe the same.

I agree that sensible mods, which have been professional fitted add value to the car and the spec. But this cannot be easily distinguished.

Another question I'd like to pose to all readers:

If you have bought a pre-modified car, what did you look for? Engine mods or cosmetic mods?

[rashg60]

A month into my remap and after driving the car this weekend it all seems to have gone kerput. The power has all gone and it feels slower than stock.

I have not disconnected the battery, nor has it been to any garage for anything. I've only covered about 200 miles in it and that's it.

I will contact R-Tech on Monday but in the meantime I thought I'd try you guys and see if anyone knows what has caused this. Has anyone else experienced this?

[AJP]

That's a bit crap to hear!

What was the condition of your diverter valve when you got the remap? I'm assuming they checked the dv, pcv etc before the map.

Bear in mind the remap will have increased the boost pressure, so any weak links in the chain can fail sooner than on a standard car.

Could be a boost leak, could be something else. No real way of finding out on here, so fingers crossed they can diagnose and address the issue at R Tech.

Update us when you can. And good luck.

[rashg60]

They checked the DV and PCV pre-map and gave thumbs up for both - saying they were both in excellent condition.

Like I say I've just covered 200 miles in it and have not thrashed it at all.

I just feely deeply disappointed as it may mean another trip down to R-Tech.

Not a happy chappie at the moment.

[flashp]

I'm sure it's unrelated. Unfortunately cars can be like this...a pain in the back side.
Sounds like something didn't like the new stress levels, engine mods can weed out the weaknesses. At least you know the engines take it well once settled.
Hope you haven't got a ridiculously long journey to make.

[rashg60]

Thankfully I'm only about 30-40 mins away so not too bad.

I hope it gets sorted pretty quick as it feels like I'm driving a 1.6 diesel about.

Any update with the issue mate?

[rashg60]

Been emailing them and calling them since the weekend - it transpires that they are closed for the week and will be re-opening on Monday 20th.

I'm being patient but I really hate driving the car at the moment. I just hope I'm not making the issue worse by continuing to driving it.

There's no odd noises or anything - it starts and drives perfect. Just the lack of power.

I'm hoping it is sorted out next week.

[AJP]

Possibly limp mode, which is intended to keep things at safe (ie underpowered) levels when the ECU detects any of quite a few different faults.

Fingers crossed.

[rashg60]

Update:

R-Tech did get back to me yesterday and advised I get it hooked up to check for any faults (why didn't I think of this!). Anyway I took it down to the local garage and they hooked it up and nothing was detected.

I was then advised by the garage owner to unplug the air flow sensor and take it for a spin. I did that and it drove much better, i.e. more power. I have since ordered a new air flow sensor, which should be fitted this evening.

Other than that R-Tech are saying change the Diverter Valve - is this something I can do at home? Should I go for the standard one or an upgraded one?
