Re mapping. A personal view .

[sonar]

Who did the remapping Sonar.

I can’t remember it was recommended on the forum when I was thinking about it.
it was some companies that has engineers throughout the country.

Celtic tuning was the company .despite what a lot of others think it was one of the better decisions I made.

sorry, but impossible.
Plugging in to the ODB port may tell them its been remapped (chipped) and possibly which parameters were altered, but impossible to determine engine power outputs let alone at the wheel outputs. Every vehicle, every transmission is different and has different outputs and losses.
The only way to determine these overall is on a rolling road measured at the wheels, or take the engine out completely to dyno it.

They plugged in their computer and said it had been remapped .

I never mentioned what the settings were. I was told it is within tolerances one would assume they whould know if it had been remapped it would have been to the approved map for the make and age of the van.

I never mentioned anything about engine outputs .
I did mention what the settings were when done on the 26 th Jan this year.

Do you need a rolling road for an old van having a much tried and tested remapp as a stage. One.

Celtic tuning say this.

All of our software is developed in our purpose built dyno cells running state of the art Dynocom 4WD rolling roads to ensure accuracy in terms of both power delivery and also to ensure fuelling, boost pressures and exhaust gas temperatures (where applicable) are all within tolerance.

fantastic smooth power curves
talk about before and after.. breathless asthmatic before lol!

Celtic tuning dId not need a rolling road to install a remapp on my 2003

there a good firm ….much used by many car and van owners.
tell them they need to use a rolling road to install a well known and test remapping
search there site type in you vans details and they will tell you what the hp and torque is now and hope much you will gain.

below is their website. enter details for possible results.

they can tell it has been remapped and what the hp is now and the torque

I never mentioned what the settings were.

maybe I misunderstood then, I read it that they were claiming to be able to tell the output just by plugging in to ODB

Devious, lying "tuners" are a pet hate of mine. It took many years and many tens of thousands of £'s to discover the truth.

No you don’t.
But your telling us that your man knows what the figures are. He doesn’t!
Yes, he might be able to tell it’s been mapped, but nothing more. (For better for worse)
“Stage 1” is terminology that has been carried over from old school tuning and normally refers to a “mild or fast road” cam and the associated fuelling and porting.

90% of generic maps out there are complete tosh.
Every one convinces themselves it’s better because they’ve paid handsomely for it.

As you probably already know, there are so called “tuners” out there that can pre load the rollers to produce whatever figures you want to see.
Like you said, very few talented people can actually remap properly. The rest is generic tosh.

 

[sonar]

Either way I have had it done and very pleased with the result.

back in "the day", one of the clubs i was in used to have regular rolling road events. One of the members was a "tuner" with his own rolling road.
We went for fun, (but I already knew what my car actually made having had the engine out for a proper dyno) it was just a "who's is biggest" day out. But the figures from his 'accurate' rolling road were sheer nonsense guestimates, not even repeatable from multiple runs.

As you clearly know, they try to determine transmission losses (to 'add' to the engine power outputs) by measuring torque against the rollers on run down after testing. And add that to the guess they made during the power run. Complete guess work,

Still fun though as I always 'won'

I think 18% is the now commonly quoted transmission loss, regardless .
They will always quote you a flywheel No too & not RWHP.

I just know the engine power a bit like a boat I knew the engine power but a fair bit vanished before it got to the prop .

I assumed the remapp was the engine but far less by the time it got to the road.
it was purchased as an engine remap .


I have no idea what the power is at the wheel as you have said that could only be told on a calibrated rolling road.
Had it been a performance car I would have insisted a rolling road and tuning at the same time.

But a 2003 Moho anything was better. And has proved to be so. At the moment.
before I would hit the red limit light in four of the gears . Not changing the way I drive so far it has not come on .

My apologies sonar, the above post was in regards to Calm Seas last post.

It was not my intention to disprove anything you have said.
A lot of these so called remapping companies and individuals get my back up, by quoting all kinds rubbish to unsuspecting people who don’t know otherwise. (No offence intended)

I’m glad that you are happy with yours and hope you got your new clutch fitted today ready the new season.

THIS is the only way to determine an engines true power output.. anything else is a guestimate.

Can you fit that engine in my transit please?
I'll be round in the morning...!

Btw van engines come in different rates of tune my transit is 125 but you can get a 155 probably a 180 by now...

there’s no need to apologise for anything and I have not taken offence.
before the remapping I did ask the forum for recommendations the best was the one I chose
knowing it was only a computer but was a little surprised they never test drove it.

Thanks I am having the timing belt water pump fan belts if there are any and whatever they think needs attention
so really just said see what needs doing and do it.
in only said this to the company as I have been told they are very trust worthy and honest by a few people.

it does not need a service did it already needs new antifreeze that’s about all I can think of.
it’s an old van that had a lot of problems. But now more spent more than it’s worth.

but loads of lessons learnt. And after have to fix repair or replace just about everything I do now know a fair bit about swifty so if anything goes wrong I have a fighting chance to fix it.

Can I ask if the "tune up" increased the cost of your insurance ? As the Insurance Companies always ask if it has been modified in any way, so (not that I am getting it done) just wondered how much extra they extract from you for a remap.

I did contact the insurance they were not bothered in the slightest.
the insurance stayed the same.
I said I would send details but they were not required.

if it had been a sports or high performance car then I think things would have been different.
