Could you,by using a WRC inlet,run 8 greens at the same time..ie split into the 4 original injector loom and power up all 8 at the same time?


Is that at all mapable on a L6/L8/P8 without the 8 injector software?....Not worried about emmissions.......in theory this is possible isnt it?????Surely an expert could do this???????

turbinator

why .. you got a bling bling S8 ecu havent you ??

Ima-Racing500

Hi...nope......using L8...dont even go there

This is a serious question..as in theory it seems possible.

Wazzzer

I don't think you'd be able to Phil cos of the voltage drop...

You'd be robbing the other injectors of a bit of their power

Thats my understanding on it anyway

CraigN

why would ppl spend so much on an ecu capable of running it if you coudl do that

Ima-Racing500

Because of emmisions and lack of mapping knowledge in the old days I mean look at Stu...750cc injectors at stupidily low CO So why cant you use twin 382cc injectors per inlet in the same way?

vroooom ptssssh

change that siggy from Bosch to Bodge motorsport dealer

Ima-Racing500

Thats me Bodge Motorsport...you wait till i show pics of my breather system

The thing is..i experiment and aint afraid too.....i love what i do...plus can get free advice from most of my customers Ok i never listen to em

But how many people can say they built a 400 plus BHP engine....a 450plus BHP engine....a 350bhp engine?...All DIY........off the shelf chips....tweaked by me...i am proud..as i have NO mechanical or electrical experience....i came from the gutter


Had problems YES....but so do professionals

Now back on topic why is this not acheivable?????Please lets not have the "i pay a tuner brigade" lets have pros answer me!

Jim Galbally

simple answer... yes

i dunno about cossie ECUs, but most stuff like EECIV only have 2 injector drivers anway and these are spliced together in the loom. no reason why you couldnt add more, as long as you dont overload the circuit and fry the injector driver (bit like if you try n run high impedence injectors on a cossie ECU)

as for voltage drops wes, the injectors receiving a CONSTANT live and are opened/closed with a switched earth, so getting the correct FEED to them isn't a problem

Ima-Racing500

So....you could use say 8 greens and half duty cycle on them and get perfect emmissions etc....but for the injectors full potensial say 600bhp just run them higher...and with the closed lambda thing emmisions good?

Surely i have now made 8 injector software redundant?


Really interested in Stus honest answer to this!

Jim Galbally

no phil, you have peak and hold injectors (low impedence) so this is certainly not the case. it would deffo need a serious looking over by someone like stu (who has done this good idling stuff) to get the fooker to even idle let alone idle legally

you have also just lost 50% resolution over your fueling... that'll be fun

and you're trying to make a component do something its not supposed to do which presumably cant be good.

you could probably get it to work, but itd costa lot of money (becasue you'd have to pay someone like simon/stu to do it as you dont possess those skills yourself) and be worse than the cheaper option... which is a full mapable aftermarket plug-in ECU thats in great demand and you got sent for a trial

phil, this question could have been answered simply by looking at either the ECU pinouts or a wiring diagram and going "oh yeah, thats how injectors work"

zvhturbo

Jim is 100% correct.

Injectors have a permenant 12v live and are operated by the ECU earthing them out.

Low impedence injectors require a lot of voltage to operate them so by doubling up you will be doubling the voltage the ECU has to ground.
Forget about the fact you will half the open duration, you will still be doubling the power the drivers have to put to earth.


Also the idea if 8 injectors is so that at low revs only 1 set operate, this helps prevent fuel drop out in the slow moving intake air.

Ima-Racing500

As said above i am NOT a mechanic or an ELECTRICIAN.....Galbally you on the other hand are obviously a geek BUT carry on as you have wound me up to a point of no return already


To everyone else..this is not something i wish to do...i am just thinkin that it must be possible for a competant mapper...as said the object was 450bhp hence why a choose L8 and NOT S8 as its much cheaper!!!!!...If i wanted 8 injectors i could easily get my L8 converted including chip for the same price as S8...and that is now what i would do as S8 has no benefits for my engine.

That you for understanding...obviously some got jealous cause i got offered a free trial

vroooom ptssssh

a very stupid idea...here but could you run 2 ecu's and get a feed off all the sensors for 2 ecu's to run another set of injectors?

zvhturbo

No mate i'm not a geek, i'm just not a total prat that don't understand anything, and posts stupid "can i do this with my car" posts.


If you took 2 mins to search the internet and read up on how injectors work you would have learnt the answer to your own question.

Ima-Racing500

ZVH you paranoid goon...i was referring to Galbally its not my fault you butted in...

Jim Galbally

phil, sort yourself out, please

you asked a question, i answered it...

just becasue the answer made you look a bit silly dont get all upset

however for a laugh i'm just gonna put up a few choice quotes that i found somewhat ammusing...


the thing is you obvious cant understand WHY that's funny... which to me is even funnier

vroooom ptssssh

i take it my idea was too far fetched

Ima-Racing500

S8 = Ł500 plus VAT plus proper mapping session from a pro @ Ł350 ish

L8 already got Ł500 plus VAT to convert including chip,needs setup/check @ Ł100

So S8 is Ł250 more......what does it do that i WOULD notice...i dont want launch control/anti-lag/the ability to fiddle with it myself...so what am i getting that i WANT for the xtra Ł250 Plus L8 is well proven

So Jim you really are a grade a cock that only dreams of proper power and no ability to actually build an engine but with an extraordinary talent to fuck up what its already got.

Thanks for all you advice but i think i will pass and favour the 90 year old across the street who once appeared in drag at the hazlit theatre

Jim Galbally

your answer is staring you STRAIGHT IN THE FACE and you can't see it

Ima-Racing500

Gotcha.........the S8 will leave a SECS imprint on your forehead when i hit you with it..ROFL

you worked it out yet einstein?

Ima-Racing500

No my good mate...no i am too clueless compared to you...please tell me mate

smartrs

oi don't put ima in with us at Bodge MotorSport he will give us a bad name

Jim Galbally

ok phil lets follow this through then...

what do you get for your 350quid (well, actually more like 500 but hey) mapping session

and what do you get for your OFF THE SHELF collins chip and setup?

also, you engine is a complete one off and nobody has ever put those components together in an engine before what off the shelf chip are you actually buying for it...

unless its a custom chip by some clever bods at colins that theyve estimated the fueling/spark requirements based on their many years of experience at this sort of thing which would then ofcourse need checking afterwards and then if it needs adjustments (which ofcourse it probably will) you'd need to get done again, and again and again

which works out the same price

by my maths, if the ECU and 8inj addon are less than 500quid you will save money but you will only save that money over the s8

so say s8 is 500quid

and ecu + addon is 200quid

then youve saved 300quid, result

you are NOT however saving money in the MAPPING... if you think you are then you ARE cutting corners... this is the fundemental thing you're missing... you're compromising yourself for the sake of a few quid... infact youre compromising yourself even more as i'm 99% sure youre not gonna get it done properly and youre just gonna buy a chip off the shelf like the last one which was NOT designed for your spec at all

DaveEscos

fucking hell phil

want me to clean the gola trainers footprints off you!

Ima-Racing500

Well said Jim........i see you in such a new light now .....I wish i'd listened to you now Gosh why am i so plain stupid?..Must be my choice of parents.

Thanks Jim..thanks alot.....your the best.

Jim Galbally

thats actually the best comeback possible there phil as i cant argue anymore

Stu @ M Developments

iTrader: (12)

Interesting proposition...


I reckon i could make it work for ya but NOT with 803's id have to use a higher resistance version and some tricky wiring, but yeah, i reckon i could possibly make it work with closed loop as well

Wanna Try?

Disabled Account

Well done Jim............good advice

Ima-Racing500

Thanks Stu for an answer of quality ......no i dont want it done as i'd expect converting my ECU to run 8 will be cheaper

Ima-Racing500

Doug....Jim is a pure diamond geezer I dont know how he does it under the circumstances...thats what makes him more special.


Ah well i just have to make do with this shit L8 now,damn i am gutted i didnt realise L8 was so inferior

Jim Galbally

phil, everyone realises that you're making some shit up about me, and it makes you look stupid

Ima-Racing500

Ok sorry Jim....your call i wont say another word Re you...but please dont stop your wonderful advice...you know i could have done with a dad like you....then perhaps i wouldnt be this dumb shit bodger

Dave Henshall

but- surely as run 8 injecotrs in pairs, why not just run 4 at twice the flow rate - less to go wrong, less wiring etc? or are thinking .... ive got 8 greens lying around for free so lets make use of them..?

Lee Reynolds

Every fooker can SAY they have.

Ima-Racing500

Oh watch out its Hong Kong Fuey

Lee Reynolds

Dont do the wiring your self Barry or it will end up like a noodle dish
