Stop talking about the evocars chip.
If makes the car feel sluggish, does not holds boost at high rpm and it has chronic overfueling. AFR's are 1:10 or less.
All you get is a big whallop of torque and then... NOTHING.

Bazza, if you're looking from heaven (or hell) forgive me but it's true.

If you want a good chip, talk to me.

Erm, you only think it necessary if racing hard? Power has increased by 50% or more, brakes are a definite.

sorry dink but then wich chip do i use?

im aiming for 250bhp to start of with 300 to much money .
lots of peolpe that have evocars chip in their 16vT say it works ok .
what do you recomand me then?

niose

it is very doable, I have made a dyno proven 250bhp+ on the standard turbo and evocars chip

Dyno graph with CRG mod list and sip

Shows 159KW at the wheels at less than 1bar on the factory turbo. KW to BHP is divide by .74 so 215bhp ATW, then allowing for a conservation 15% tranmission loss (normal 20%) 215bhp at the wheels is 253bhp engine, with 20% tranmission loss more like 265bhp

Crg there is no reason you won't get similar with your mod list

Cheers

Mine´s at 259hp and 395nm of torque still with original turbo with Evochip
And holds boost very well (now much better with the ACDELCO), supersprint full exhaust with decat, Kn filter with drilled airbox, balancer belt removed, Evochip at 1.4bar, DV006 dump, 3bar fpr.
I tested in 2 diferent rollers with just the 3hp difference (the other one gave 262hp)
Maybe help the car doesn´t have much km´s

ok guys thanks im going for it !!
only saint and paulinho what do you guys think about a manual boost controler like the turbosmart it costs 35pounds to the more than 150pounds that the electronic ones cost.
im going to take the coop tomorrow for an electronic chek up to see that everything is ok before i star.

Saint, your test was done with a boost controller right, the evocars holds about 13psi (0,9bar) at midrange and around 10psi (0,7bar) at redline.

Any chance you have a graph Paulinho?
What was your AFR, were you wasting fuel for nothing or not?

to BLUEMAN : yep, I had alfa 155q4 with +320hp and original brakes.. stops good. same brakes, but 200kg more weight. but if having some extra money and wanna be sure.. of course. and me myself, I m gonna chance originals for bigger one..

Dink - yes it was, it was set to max duty up high so that was all the turbo could pump but it still kept making more power so I let it go


CRG - boost controllers, I think I would go upraed EBC as per Vas's suggestion then stright ti electronic, manual have the downfalls of of electronic (ie remove ECU safety features) without the benefits. The uprated EBC's fix the boost hold issues as per Paulinho's post above

DINK: we all want to know what is the good chip, if evochip is not ?

jtm,

you have your fuel pressure at 3,4bar, i don't know how much boost you are running at the top end nor how much at midrange. How do you expect me to give you a plug an play chip?

Point is, people are modding their cars with god knows what and then ask what's the perfect chip? That would be a livemap.

If you only care about max power and the corresponding AFR at the top end, the evochip isn't too bad because it gives a margin for error.

Is it more responsive than the stock chip off boost? NO, it's worse
Is there a massive difference in ignition advance in high rpm? NO
Is it more economic even when you're not bootin it? Nope
Is it maybe overfueling off boost and midregion? Yes
Does it give more fuel at the top end than the stock chip? Just a little bit.

I can provide a good chip that gives you out of the box around 230hp with more top end power than the evocars and a fuel efficiency better than the stock one or the evocars.

I'm not recommending it but it can be used with a boost controller, a slightly bigger turbo 60trim for instance, 3bar regulator and a good FMIC to give around 270hp. yes you need to verify the AFR and EGT if you want to push 1bar at the top end. More than 1bar top end makes the EGT's rise dramatically.

"the evocars holds about 13psi (0,9bar) at midrange "
Wrong! 1.4/1.5 midrange and 0.9 redline (due to turbo limitations)
The Evocars chip is indeed more responsive and drivable of boost
Massive ignition advance on in high rpm maybe not very good for engine (it´s really massive off boost and that is one of the main reasons why the car is more responsive off boost)
About the fuelling issues i don´t know cause i never checked that.
I run this chip for 4 years and for me it´s the election chip from those that i´ve tested (Evocars, Superchips, Abarth and Dimsport)
Eaven the Dimsport one is a reaaallly close Evocars chip

The feedback that i´ve got from the chip is very positive overall but i also doesn´t say that there is no better then this.
About the print of the rr i think that i´ve posted in FCCUK some time ago

DINK : 1.4 bar pressure and livemap.

and for the evochip goodnes: walbro+3.5bar fuel+gt28rs+evochip etc = 340hp afr at around 12 in high revs. so no livemap.

No comment.



BOLLOCKS!

It's overfueling on every single car we tried it on, the moment you even touch the gas the AFR is dropping to 1:11.
Driving 120-130km/h it's not even in the stoich range, more like 1:13!

I won't comment on this any more, i don't fight for a lost cause!

JTM---> With 0.86 A/R housing right?
I would also like 300hp but without much lag

yep .86 A/R

crgracing---> I´ve tested the ACDELCO valve and i was very suprised with it!
It´s really cheap and works very fine, with it you also still have the safety features.
I had one "ball and spring" PRV and it didn´t work to well cause sometimes the ball was stuck and the car had massive overboosting causing the MAP to "cut" the motor.
But that was my personal experience with it. You know that like everything, there are good things and bad.

but the EBC is very expensive where could i find a cheap one?and would it be a problem if i use a manual boost controller?
paulinho the ACDELCO valve is it the blow off ?

Nope...
The ACDELCO is a EBV (electronic bleed valve) like our standard one but it works better (That is the valve that the ECU uses to control the turbo boost).
I think that you are confusing with a BOV (blow of valve or dump-valve), this one is used to discharge the compressed air when you lift of the throttle for not stalling the turbo.
About this one i am using a Forge DV006 with the softer spring (yellow or green i can´t remember), but it´s a little for the expensive side.
If i am wrong, anyone please correct me here

Your Right Paulinho

When my car was "standard" i did also use the evochip, and i think it is a great chip.

paulinho dont know what the electronic bleed valve is, where is this valve ? is there any images ? if i see it maybe i will recongnise it.
for what i understant i nid the EBC and the EBV wright?
thanks guys

+1 on what dink says I'm afraid.

Tried evocars chip on a few cars down here. Smell of petrol, overfueling badly, crappy idle, engine check on unless you blipped the throttle, etc.
Oddly enough, it worked relatively OK on mine (ONLY out of 4 cars tested!)

Couple of the guys came back to me saying they wanted another chip, so eventually started delivering a cross between something that dink gave me months ago and puceabarth.
Slightly less push, but car runs stoich on cruising (no 13.2AFR at 3Krpm for no apparent reason, unboosted) and it's good on fuel. Decent morning starts as well

V.

Easy to find
It´s the cilindrical shaped part with 1 pipe on top and two at the bottom with a electrical plug.
It´s located on top right of the radiator
No need for an EBC, you can use the EBV that it´s controlled by the ECU (standard EBV is pierburg that must be the one that you have or an better one like perrin, acdelco etc.)

About that puceabarth file...
JMA at the time send me that file, like it sent to you also.
When i checked the file it was 100% equal to another that i downloaded from the net before he sent me.
Check the idle and also injection and ignition rpm breakpoints in that file.
Who guess what car is that file from?
About the blip in throttle for the injection to go out usually is TPS sensor not chip fault.
Evocars chip gives the injection light error (due to an eprom checksum fault) but it´s just during the first 15 or so seconds.

that's easy, delta EVO2

No...wrong
That file is from a Ford Escort Cosworth, same Weber-Marelli IAW P8 management system.

and ignitionlight on , right ? =) the evo-chip is out of date .. there are sure some better chips available but the best is still a livemapping ..

(ps: the german grale guys are lougthing on evocarchip users .. )
