Advice Needed.

[jay m]

Hi folks,

I've been trying to carry out a pulley upgrage on my tte s/c and had nothing but trouble since. I'll skip all the boring rant and get straight to the point, basicaly the kit i bought was a larger pulley, gredddy e-manage ultimate ( with - boost presure sensor with harness and the uiversal harness to wire it in ) Also bought a set of 550cc injectors to take care of the fuelling situation.

The stuff above was all what i was told to buy from various people i spoke to etc so i spent about 4 months trawling the net trying to find the best prices etc book it in to the garage to get it done and regretted every minute since. After it being in the garage for 2 and a half weeks costing me a fortune i get told i require a harness to controll the injectors as they have been changed, this makes sense! However i then get a phone call saying that greddy do not make a harness for the injectors for a is200! He went into various details of how it coul be controlled through retarding the timing etc but it wouldn't be reliable and wouldn't preform to its full potentiol (sp?).

This concerns me becuase i know that others have used a similar set up in thier cars and this is where you guys all come in, where do i go next, do i give up now and get the car put back to the way it was before or is there alternative? Does anyone know of any other solutions to the harness problem, i.e does one from another car fit etc, or should i buy another ecu which can catter my needs, i guess a standalone would be ideal how ever i am completely out of my depth here and seek some knowlage from thoes who know.

Any help much appreciated guys,

Gord, Pro-Lex or Sparkystav might be able to help advise you mate. Best of luck with it.

I'm afraid mate the best person to ask may be TDi but they used a HKS FCON i think. POossibly speak to Hyper sports and performance in Wigan? i know they've fitted an Emanage to IS200 so maybe they can help?

Surely though thinking about it, injectors only differ by their resistance, and theres only a couple of resistances used, so surely the only thing stopping you connecting the injector harness is the connector plug? Surely this could just be cut off and soldered on or something?

Just my thoughts anyway.

But to be honest like i said i've not heard of one thats ever worked properly, but to be honest with you i've never heard of a supercharger will pulley upgrade thats actually worked properly.

Hope you get it sorted though mate,

Stav

Edit: also have a look at Carles reply to another topic here: Clicky

[Dave-Ellen]

you need to speak to greddy to ask for all harnesses for a forced induction is200

[sparkystav]

You speak to greddy mate?

Stav

[tunamgu]

jay m,you got to empty your inbox.i have to ask you something.

can ask here:how many mm have you lowered and what brand?coilover or springs only?

[jay m]

The update:

After speaking to greddy etc they all seem to say the same thing, the universal harness which i bought does have the capability to controll the injectors, i got the wrong end of the stick. The problem is that because the new injectors were installed the wires from them to the standard ecu have changed or something. I personally dont understand why they can't just be soldered back on, im not all that clued up on the electrical side of things and just cant picture it in my head at all lol. Going to go down tomorrow and see what he's saying, he basically said that it wasn't do-able and wants to give up by putting it back to the way it was when it went in and no doubt charge me a heap for having it there for 3 weeks and all the labour of installing all the ecu etc.

By the way tunamgu my inbox is now empty, sorry, aint been near a comp for a few days, and yeh i have the tein superstreet coils, unsure how much it was lowerer by but its low enough to hit the lip off kerbs, as ive found out several times, and thats not rite the way down either, my wheels scuff when hitting bumps etc when lower.

You might of been better off driving down to Wigan, for Hyper to fit for you, as he knows what he is doing, you would have got it all fitted and running for less than £500 :D

[jay m]

Well i wont say how much i was quoted but it was almost double that, wish i knew this to start with, even counting the 700 mile trip i would still be better off, bet it wouldn't take 3 weeks to be returning back to what it went in with either

will be keeping that in mind!

I just dont really know what the problem is, the guy might as well be speaking spannish lol. Will see what he's saying tomorrow night though, getting fed up having to drive my old escort van everywhere, i want the lex back lol.

[sparkystav]

Gutted for you mate.

Hope you get it sorted in the end.

Stav

[jay m]

cheers mate, will report back tomorrow!

i have seen injector connectors for sale on eBay

[jay m]

Well, where do i start lol. Basically the outcome is that there is no safe way of controling the injectors etc with the e-manage ultimate. It would be possible to lie to the ecu etc and retard the timing so that the fueling would be compensated but not really ideal. Looks like for this to work then it would have to be a stand aloe ecu for the job thenn it would be able to fully control the engine rather than only doin some of the work.

Should i leave it or keep going, i'll wait to see what the bank account says......

[sparkystav]

And why can't it control the injectors? Who told you?

Is it because you've cut wires or just not possible ever?

Sorry for all the questions, just wanting to do this myself at somepoint.

If you was to use a stand aloe ecu to control you engine full, it would cost ££££££££££££££££££ just to map it :shutit:

[jay m]

Well from what i gathered it is because it is having to send the signal back through the standard ecu which would confuse it, the method of fixing this would be to lie to the ecu so it thinks everything is fine then to take care of the fueling etc you would have to throw off the timing by around 6% but this mean that when theres say 50% throttle the ecu would only think its like 40% thus leading to problems.

Still trying to get my head round the whole situation :duh:

sorry thats complete bollox.

when i did adrians car i drove it as we changed the duty cycle on the injectors i could see the data on the laptop as it was altered and felt the car driving differently.

i reckon its not been wired up correctly

[jay m]

this was my initial thought how ever i dont have the technical know how to argue. Would it be possible that he got the wrong instructions or something?

i have missed out on several oppertunities not having the car which i was guted about and that was fair enought but now that there is reason behind the doubt im beyond confused on how to handle the situation.

[sparkystav]

I've been reading up on the wiring for the Emanage ultimate and i'm sorry mate but that doesnt sound right to me either,

From what i can gather you cut each wire coming from the ECU and put the Emanage inline with it. So in my way of thinking. The emanage sees the signal sent from the ECU, alters it to what it needs to be, and sends the signal back out to the injector.

Can i ask, was it the garage or Greddy that told you it couldnt be done?

Stav

[jay m]

It was the garage, i think the confusion started with there not being a harness made for the is200 and having to use the universal one. My heads spinning!

[sparkystav]

Its not hard using the universal one, theres wiring diagrams and everything in the standard instructions.

I've pretty much figured what wires need to go where before i've even got one.

From what i've gathered the only thing the iS200 MAY need apart from the universal harness is the boost sensor, but thats a maybe, i'm not 100% on that one.

Stav

PS This is all from my own research not what i've been told by a garage or anthing. So dont say its gospel

[jay m]

This is correct mate, it is needed with the appropriate harness too!

[jay m]

Getting confused again, this is how the conversation went ;)

"Rite so it gets all the data like were the crakshaft is blah blah blah

then it will tell the injectors ow long to stay open for and how to fire the spak plugs...

So the idea with the piggy back is you disconnect it, the standard ecu feeds the piggy back and then you tell the engine what you want it to do. So your sort of intercepting it and lying, but as soon as you try ad lie the standard ecu switches over.

Now i spoke to ****** and he said the greddy manuals on the net they do igition and injection adaptors, so basically these tell the standard ecu that everything is ok.

ME: So does this mean it bypasses it?

: No it doesn't bypass it, it intercepts it in a different way or somethin, im not 100% sure on that. And when i e-mailed mohd parts they simply emailed back and in one sentece they said that im not aware of any harnesses for that car.

Now the way its wired in at the moment we can alter the map signal to the ecu which basically is the load refference. So the load reffrence coming from the center to the ecu we can intersept that ad lie to the standard ecu about the load. Rite, now the problem with just doin that is say in one area your getting too muc fuel, you can say the loads not that much, its not worth it, and instead of the standard ecu thinking youve got 50% throttle youve only got 40% throttle. So it wont add as much fuel, but it will aslo add ignition timing, which is what you dont want it to do, which is why you want the igition and injection seperate.

So you can go in, retard the timing by about 8 degrees, fix all your fueing, tenn once thats sorted you can go back and start on the ignition timing and advancing it to a safe level. Which you cant fo at the moment which is wht i wouldn't F*** with it. And another thing with the bigger injectors youd have to change the load reffrence everywhere just to make up for the injectors wth the already advanced timing."

Does this make any sense to anyone lol.

Jay, who are you using in Aberdeen to do this or try too ?
