Remap 1.8 remap deal

[nemo]

hello people, got my 57i on order coming soon

a mate is now doing remaps and has offerd to my 1.8, now before you all say its not worth it for the money, hes said he'l do it for £180 which is a wicked price £80 for the file and £100 to do it.

im under the impression that a remap on a N/A petrol engine will give you between 10 - 15 percent increase in performance. is this true?????

because if it is then i think for £180 its worth it for that extra bit of pull. what do you guys think??

[Relic]

This really depends on how drastically Honda have detuned the 1.8 with the ECU.

If the engine could only ever put out 145 BHP anyway....then a remap is not going to make significant gains and you'll be fighting with numerous other mods to see only moderate gains.

If they have put a realy restrictive exhaust on the system...then you'll get really good gains with a remap to suit a modified exhaust.

Like wise if the induction system is restrictive....then you'll get good gains from changing that.

No one has really done serious tuning on the 1.8. So no one really knows what the 1.8 is capable of and what the true base level is.

It takes time, money, experimentation, and lots of dyno/mapping time to find what the engine can do. Even then each engine is unique.

But its basically a question of finding a bottleneck, removing it, then finding the next bottleneck, removing it and so on.

thanks for your answer. think the BHP of the 1.8 is 138.

im changing my induction to a k&n when it arrives hopefully shortly, and am considering the invidia exhaust so maybe then with these on my car a remap might add a little extra power.

all i was thinking was for £180 it might be worth that little bit extra. i would never pay the full wack for a remap on this car because it just woudn't be worth it like many have said, but for £180 think im gona give it a go

I know the standar BHP is 138...But they use the ECU to drop the BHP to the desired/planned/quoted figure. They only have to change the ignition advance and fueling to do this.

Yes...its definitely worth doing..but you'll need to get your mods on their before the remap. I'd also recommend going somewhere with a rolling road to get the figures beofe and after.

Some people who have done the process properly make a mod...rolling road it...make a mod...rolling road it. Just to see what is working and what is not working (at the moment).

You could find the K&N does nothing on its own. You might then sort the exhaust and get a good gain. But if you applied a k&n now you might also get a good gain from that as the exhaust might have been the bottle neck that needed fixing before any induction gains would come.

Hope you follow

Techinaclly it should be optimised or remapped if you prefer after every mod.....but that gets pretty expensive

yea

thanks relic big help ** cheers

I'm going to sound like a bit of a git for saying this but £180 for the file and application wow, I know my time is worth more than that, it would take hours to define which parameters to change, make the updates, test the updates (the mapping will be 3d). Modern ECU's use claculations rather than 100's of sensors measuring every element, if you amend a parameter in one location it could be read in another, either meaning one of 3 things, 1 pop goes your baby, 2 safe mode warning codes or 3 the saftey features on one element of the map negate the changes in one area.

There's also the physical fail safes. If you increase fueling to up power it's not uncommon for the exhaust sensors to notice the gain and throttle fueling back down.

Whilst there will be an element of tolerance in the 1.8 for reliability 138bhp from a 4 cylinder, SOHC 8 valve engine is pretty close to optimum I would say.

If the 57i is like the others I have seen you may well see a fall in power. It will suck in a lot more hot air and the routing may not be as efficient or as 'tuned' as the original airbox.

Thats why poeple pay pros good money.....
.....hopefully they know exactly what they are doing

Doesnt stop you getting a numbskull who charges way more then he is worth

Or a genius....who happens to be a mate and is doing part cash part favour.

this is exactly how it is. i know i put - quote : ''a mate is now doing remaps and has offerd to my 1.8'' hes actually been doing them for a long time but is now goin at it alone and has done alot of cars. hes mapped my cousins leon cupra at three different stages with amazing results

[Relic]

Good luck matey....give him time to understand your car. Might take quite a few sessions for him to suss out whats what.

[Guitaralmond]

I dont think you will ever have 10 to 15% on N/A. Yes on a turbo but i reckon if flashpro gives 5bhp on a Type R 20bhp on a 1.8 is living on a dream world..

[Relic]

We dont know how detuned it is if at all as you say.
No one I know has done serious tuning on the 1.8.
Might get 1% might get 10%+.... noone knows.

Just cos the type R has been pushed to the limits by Honda....making it difficult to get further gains....doesn't mean the 1.8 has

We only know of the Type R limitations cos of the amount of people that have tried to tune it.

I think that remapping the 1.8 would be an exercise in futility. Its not an engine buillt for performance and I doubt you'd see a 13hp (10%) increase afterwards

That may prove to be the case....but if you dont try you never know

[nemo]

obviously im with relic on this. for £180 i think it would be worth tryin out.

as it stands now the majority of people on here might say that the 1.8 will get no gains from a remap. so apart from £180 what have i got to lose

if its pays off i would have thought alot of 1.8 owners would be interested in doing it.

if it doesn't pay off then oh well ive took one for the team and proved that this car realy has nothing left to give

Youre mistaking the 1.8 for a performance car, its not, its an economy car. The Vtec is working in reverse to what youre hoping...

Although Im still looking forward to the outcome..

Maybe a new engine?

Roush have a massive amount of resource and 100's of people with years of experience of working on Ford's. Even with Ford's input it took them 3 years to produce a re-map for the Focus ST. There are so many variables without a thorough understanding of 'that' car and a degree in mathematics no one can simply re-map a modern ECU in a few hours and with just one attempt.

agree with guitar almond on this one fellas..

you get 10-15-20 on turbo diesels
around 10-15% on turbo petrols..
on an N/A

we will see approx 4-6 hp

then why do we get the 2.2 cdti to 190 BHP ???
thats more than a 20% increase its around 70%

were all on the same side here, i jus want to know if its possible.
has anybody else mapped the 1.8 before??????

i might report back to you guys in a few weeks saying i gained jack s**t
big deal! i tried at least

The diesel has a turbo which you just turn the boost up on.. very easy gains!! My friends 1.9 Golf diesel has gone from 115bhp to 170bhp Celtic tuning too!!

But in the 1.8 unless you have someone there with TPW from tdi kind of experience mapping cam angles and proper VTEC mapping (if possible) then you might be in with a small chance of 10 bhp at the most..

Otherwise you "friend" is prob going to blow your engine right out of the bonnet...

Just my small experience making a comment, please dont let me stop you modifying your car in what way pleases you. I just would rather not see a horror story if i could have helped prevent it...
