well as my signature says i'm shortly embarking on a a few more mods for my car - at the moment due to the non-supply of straight induction pipes looks like i'll just have to use the existing pipework for the apexi power intake then do a swap over when barbz gets some pipes in. everything else should be straightforward.

but ref my unichip, this has a boost module attached to it and i'm not 100% sure exactly how this works or how an ebc will work with it? as far as i'm aware pts install/map to the standard unichip only. would installing a blitz ebc create problems?

hoping for around 280-285 bhp @ 1.2 bar with a gtec2 chip - is this realistic? can't afford an upgraded turbo just yet... <img src="/forum/images/graemlins/frown.gif" alt="" />

With an EBC the boost module will no longer control the boost. This will give better boost response and will be fine if set to 1.2 bar and the the car is re-mapped to this boost profile.

I would say 260-270 bhp mapped on that lot as long as your turbo is in good condition and can hold the boost at the top end OK.

why are you planning to put a Gtec2 in if it's already mapped with a unichip? <img src="/forum/images/graemlins/confused.gif" alt="" />

also i'd be surprised if you managed to get 285 from a std turbo, that's usually hybrid teritory.

I got 275 with my std turbo and unichipped at 1.2 bar, but I gather from Barbz, that when the unit went into be refurbed it was just junked as the whole thing was shagged, due to running that much power for so long. I don't think anyone else has reached this power on a standard turbo.

Also, agree with Kenno, why gtechii if you already mapped to a gtechi. The unichip should be pulling as much from the car as safely possible, I doubt whether you would see any gains from a ii. Unless you remap again, but even then I would expect the increase to be minimal vs expenditure

Most of the standard 20vt chipped here in denmark end up running at 272-280 hp, this is standard turbo and everything else, at 1.2 bar i believe

what with just a chip <img src="/forum/images/graemlins/shocked.gif" alt="" />

i don't have a gtec 1, just unichip mapped over the standard chip. putting in a gtec 2 now should be ok with the mods i'm running especially after a remap. also thinking of getting aquamist installed at the same time as the remap to make use of the dual map on the unichip whilst also looking after the extra ignition advance the gtec 2 will give me. therefore more power without having to increase boost too much and hopefully protecting my turbo and pistons.

anyway, hopefully only about a 2 month wait till i can get a superspool.

Do you have an increased fuel pump / regulator / voltage mod?

no, was hoping the standard pump will do for the timebeing. am sure pts will let me know if i need a 255. think it's borderline around the 270-280 bhp mark for a standard pump to cope.

Yes, just chip on fully standard car. Have seen a 20vt with supersprint cat-back and thats the only mod, plus a chip, then 279 hp

if your car's been mapped with the standard pump and there's enough fuel for them to play with there why go for a bigger pump?

Same goes for the chip - dont mess with a setup that works fine already

any changes to the fuel system / or different chip and you'll need a remap....

i agree but putting in a walbro 255 safeguards for the future, the more mods i can get done in one go the less i will pay on labour costs. also my car was originally mapped to a ragazzon exhaust, even without changing the chip, with a new exhaust, fmic, filter, aquamist there is no way the fuelling would be spot on.

fair enough - if you upgrade the pump you also need to modify the voltage IMO to ensure the pump get 13v under load - the standard wiring wont give enough power to drive the bigger pump properly as it can drop as low as 9v on some cars which = approx 30% less fuel than at 13v.

If you trawl through the PTS result post;

a, you'll be reading for weeks
b, you'll find that Paul thought the Gtec1 was a very good chip to map over. A number of guys (myself included) had a very similar setup to yours when we went up there for the remap using a Gtec1.

If you do want to bung a Gtec2 in then fair do's but i would say that it may be worth taking a Gtec1 with you just incase. <img src="/forum/images/graemlins/smile.gif" alt="" />

edited to say: Wouldn't the final outcome be the same regardless of which chip was used or is the '50 points' that paul can play with not that much? <img src="/forum/images/graemlins/confused.gif" alt="" />

You want the car to be running slightly rich prior to mapping - in the 10's so they can pull it out a bit to get more power but still be safe - mine was mapped to 11.9 and gave me another 10bhp, which is slightly conservative, but I want reliability not another 3 bhp ontop of that....

The GTEC2 feels more response off boost than the GTEC1 as the ignition is advanced. Another feature of the unichip is that the ignition is advanced until the car starts to DET and then backed off a bit. It's easier for them to play with the ignition timing from the GTEC1 aparrently.

As long as whatever chip you use is fuelling well througout the range + your car can support what the chip is trying to do (e.g. if your injectors are filthy then using a higher fuelling chip will not increase the fuel delivery)then the unichip should give the same result.

Different chips perform differently in different cars. Dave at PTS said he has seen some coops with pretty much identical setups fuel totally differently. In theory a plug and play chip like the GTEC2 could be spot on for your car - and you would gain very little out of a unichip at all!

if you want to make sure you'll get the most out of a unichip then you need to get your hands on a wide band lambda or go for a standard rolling road run to iron out / spot any major fuelling probs if there are any + then sort them out before you fork out for a unichip.

unichip and boost module was installed by the first owner so it's just a case of a remap. think i'm going to do the filter/fmic/aquamist/gtec2 (standard fuelling) in 1 go then remap and see how much i can get out of the standard turbo.
