Came in the post today fitted it in 10 minutes .I hesitated from buying on as i don't want a turbo car 20VT with on and off power delivery . My 16 VT is a bit laggy I am impressed with it . The car seems to have more low down get up and go . I have a boost gauge fitted and just put a new clutch in the car . Only driven the car up and down the road so far . Well worth the money .

Gtech just takes the boost limiter off 1st and 2nd gear which is why you're feeling like it's got more get up and go, fine in the dry but gets a little too lively in the wet for my liking.

It doesn't "just" remove the boost limiter in 1st and 2nd gear. It increases boost in all gears and also modifies the overboost, fuelling and ignition timing maps.

Almost every coupe tuning chip removes the boost limiter , as does using a manual bleed valve or (almost) any electronic boost controller. So if you have a particular desire to be able to floor it in 1st and 2nd without spinning the wheels in the wet then you'll need to be running with no performance mods at all and also with some incredibly good tyres.

I stand corrected

Hi GrahamL,

Do you have any spare and how do I get in contact? I can't private message you on the forum.

Sorry to hijack the thread.

Ratz, you will be able to send PM's after you've made a couple of posts.

Search on the bay for Gtec and look for the seller 'Traumax' it's Graeme.

you can contact him here if he still has a Gtec 1

Edinburgh sorry,
i didn't want you to appear on what i have but i don't know what i selected. Excuse me

Banned!

I'll send you a PM, maybe you can reply to that?

Hi my friend.. i wanna ask u something about gtec chips.. can u write me from whatsapp please? +905334600560 , thanks

I don't have a smartphone and even if I did I wouldn't be installing any social media related stuff on it.

I'll drop you a PM on here.

<edit> Apparently I can't PM you it says you're over your limit, maybe you can try sending me a PM?

Graham, he's only posted once so PM-ing will be restricted until he ups his post count.

I'll send him a PM to let him know.

I cant pm too:( can we talk from phone Graham?) &#304; have ur gtec1 chip, my friend gifted me several years ago. But i heard that it should be mapped specific for my car and my countries fuel octane, and now i will put hybrid stage 1 turbo, bigger intercooler, i have complete supersprint exhaust, do i need gtec2 or gtec1 is enough for my car? And i m living in Turkey, in my country it tells fuel is 95 octane but when measured, it is 90 octane maximum. Gtec1 is for this fuel mapped? Tnx

If the fuel is only 90 RON you could add octane booster to every tank when you fill up, but otherwise I'd stick with the Gtec1 if it's running OK and spark plugs look OK, or even consider returning to the standard chip for safety especially with a hybrid turbo. Definitely wouldn't run a Gtec2 with 90 RON fuel, even with an uprated intercooler.

With hybrid turbo and bigger intercooler, which one is best? Gtec 1 or standard eprom?

And with gtec1 , hybrid turbo, how much hp i can get? And u recommend water spray kit for intercooler to get more hp ?

if you only have 90 RON fuel, I wouldn't run anything other than the original FIAT chip and use the Pierburg EBV.

With fuel so low in RON ratings the chance of pre ignition is high, pre ignition equals detonation and detonation equals broken ringlands on the piston (normally number 5 cylinder)

Albeit I appreciate this might not be cheap, but if possible get your car custom mapped, so that the fuel quality is factored into how the car runs, at least then you'll probably be safer than today

If you're prepared to add octane booster to every tank I'd use the Gtec1 and keep an eye on spark plug condition. If you're not using octane booster and the fuel is as low as 90 RON then I'd stick with the standard chip especially if using a hybrid turbo. And don't use a boost controller (either electronic or manual), let the ECU control boost via the EBV to retain the safety features allowing the ECU to retard the ignition in case of knocking.

I checked internet about octanes of fuel in Turkey.. our octane info is 95 octane and 97 octane , 2 options i can buy. U recommend 97 octane for me? And i m living near the sea, so google tells in my city octane is high:) so gtec1 or gtec 2 will be good for me with hybrid turbo? I will not use oem epeom i think with these octanes.. and how much hp i can get with this combinations? u recommend water spray kit for intercooler to get more hp ? Thanks.

If the fuel is inconsistent then use the highest octane you can and consider using an octane booster.

Gtec1 will add around 20-30 bhp depending on other mod's and state of the turbo and EBV, Gtec2 maybe a little more but mostly it has more aggressive ignition advance low down hence it should only be used with an uprated intercooler for safety. If you're in any doubt about the consistency of the fuel octane then I would definitely not use a Gtec2 at all, especially in a hot climate like Turkey.

A hybrid turbo will add around 10-40bhp depending on the exact spec. and what boost you run it with.

Intercooler water spray I had on my first coupe and it didn't make much difference.The biggest difference it made was that people kept saying "Do you know you've got a leak at the front of your car there?" while pointing at the puddle. Maybe it would make more of a difference in a hotter climate than Scotland though

Hi again my friend, i have bigger intercooler. so if i use 95 octane with my hybrid stage 1 turbo with gtec1 chip, it will be perfect match? And probably 30-40 hp i can gain in total? And ur chip is suitable for Turkeys climate? My car also has complete exhaust with sport cat and sport headers..

If (and it's a big IF by the sound of it!) you can guarantee the RON of the fuel to always be at least 95 and you keep the boost at no more than 1.2 bar sustained with the standard turbo then a Gtec1 should be OK. But with a hybrid turbo and the very hot climate it would be risky if there's any doubt at all about the fuel quality, even with an uprated intercooler.

The safest thing would be to just use the standard chip, but if you really want to tune things then I'd get the fuelling checked properly on a rolling road or even better fit a wideband lambda sensor as was mentioned over on the other thread today, that way you can keep an eye on the fuelling yourself at all times. Maybe also fit en electronic boost controller so you could reduce boost as necessary if the AFR starts to lean out due to bad fuel and high intake temps.

Hi again my friend, how are u, i hope u are okay&#128522; i wanna ask u something, in my stage1 hybrid turbo, with gtec1 chip, in my turbo how many bar i can use ? 1.4 bar is okay? Or max 1.0 bar i should? My stock engine can be suitable for high bars or i should stay in 1.0 bar? &#304; attached manual boost controller and i can change the bar.. but which one is best option for me? Thanks alot..

I've replied to your PM.
