Hi I'm modding my wrx bug and so far put fuel pump and 700cc injectors in it ready for the up pipe , turbo and exhaust next week (time permitting)
when I fired it up with the new injectors it was running like a bag of bob
As you would expect
So I've dragged the map out had a fiddle (change injector scale , latency, tip in )
On the whole it drives good but there's a very slight hesitation that seems a little random (and I mean slight not bad by any means but I know it's there)
All the figures look ok , idles well , not lumpy ,I'm running it slightly on the rich side for safety till the other bits go on and it will be mapped with a lot more attention to detail
What I was wondering , can a standard bug fitted with 700 cc injectors be mapped to drive perfect , basically the same as a standard car
I've not spent much time trying to be honest as like I say it's all change pretty soon
If it can be mapped to run perfect should I do it (in light of the mods to come)

 

Why have you gone for 700cc ones? even your engine in standard form wouldnt see much benefit from them, the 550cc sti ones are a better upgrade and cheaper, and no matter what, you will need to have the car mapped to make the most or else you will be running too rich, the ecu is only so good you know
What other mods do you have on your car?

Got 700 because I've got plenty of scope knowing that down the line they will cope with 500+ so I've not even got to consider upgrading again no matter what mods or engine I use
Like I said I've mapped it as a stop gap to run with them till the rest of the bits and bobs go on
And have no intention of running a standard setup with 700s and expecting great things ( that's not my intention )
Like I said the turbo , pipe ect should be on next week (and it will be mapped again )
As for the ecu , there are no problems with the standard ecu for a reasonable bhp road car , l/c and a/l are the only thing that I know that can be ,shall I say not the best suited , but that said still can be done (sort of in a fashion )
For what I have planned there is no need whatsoever the for an aftermarket ecu
And I'm certainly not goin down the (I've got to be honest) rip off ecutek route
When will folk realise its the mapper that's important not the software
My question was for curiosity's sake more than anything
Could a good mapper get 700s to work perfect on a standard bugeye ?
Not that I intend to at all , well maybe for this week

Sorry tony I've got the wrong end of the stick when you said the ecu is only so good ,
I guess you mean only so good at sorting fuelling ect when you bung new upgrades on the car
Yeah I know what you mean , that's why I've spent what feels like forever looking at maps editing and chucking them in , so it's not got to think so hard

 

Yes a mapper can get 700's to work fine, still they are waaaaaay beyond what your engine can handle, wrx engines are not that strong you know
As for the ecutek v OS, id go Ecutek everytime tbh, mainly because the mappers are vetted, ok you have to pay the license but its cheaper than a new engine

Yep agree 700s are pointless on a standard motor
It won't be too long before they are called into action and as soon as that's complete and the bhp starts to arrive its then going to be forged time I guess then transmission shortly after that , never ending lol
As regards mapping 700s on a standard motor ( pointless really I know )
I wasn't sure if it was my lack of input in both time and knowledge or 700s would be a tall order to get spot on with a standard motor
The ecutek or o/s debate , some great mappers who are highly regarded
Freelance and will do both , so paying for a licence seems madness to me plus after the expense your ecu is locked as an added bonus
Me thinks this bad mapping engine blowing scare is the perfect seed for the ecutek mapping business ( only my opinion )
What ever floats ya boat , but I can't subscribe to that one I'm afraid
Has there been a thread about ,who's had a motor go pop due to a proven bad map ?
