and yep 3.5 hours seems fast to me too but they appear to have done a good job (and they had tuned a Haltech G35 before)

If they had seen a G35 before and tuned it with Haltech, assuming they had similar mods to you, then they would be able to tune it quickly. Will also benefit others who do the same as you now, as they have your map as a base, so anyone going with similar mods might get it done even quicker

Not a pro in this area but heard you cannot really use maps between cars anyway since there will be certain difference that can't be accounted for? Pingu, do you have access to the ecu or is it locked down?

(sorry ment to say not 100% exchangable...)

results were on last page of this thread... as is a link to TDI blog..

Sorry mate , did not understand that was your car

nice colour

OK - picked up the car this morning and drove it home (about an hour)... the car is much more driveable than ever really, picking up much much better from 3000-4000 rpm particularly (and also not tailing off past 6000 although I only got to try that once!).. gathering speed from 80 to 100 in 5th on the motorway it feels significantly improved - you put your foot down and stuff seems to happen quite a bit more quickly.. I would say the car is 10% faster

 

the car starts and runs perfectly fine and there are no problems noted so far! both me and TDI were pleased with the results, especially in the torque curve!

 

to give some indication of the cost:

 

total cost is hard to quantify as I had some other work done at the same time, however fitting the ECU must be under an hour and TDI used 3.5 hour of dyno time to tune the ECU (most of the gains came from adjusting cam timing) at £95 an hour..

 

so lets say 400 quid fitting/tuning and the ECU was 965 - and then add VAT = £1570

 

more impressions will surely follow over the coming week or two

Dyno results?

3.5 hours dyno? That's fast working , sound writeup!

no but they are fine for most uses - the Haltech is really overkill (and futureproof) on my part I guess :/

will do - its going in next monday

I wait with baited breath!

 

Probably missed this but who is doing the work for you? And what dyno do they have?

 

Will be nice to see results from a more well known member on a proven dyno

 

TDI in essex are doing it.. not sure what to expect, but I view it is a base on which to build

 

they have a "Rototest VPA-R chassis dynamometer".. I believe it is pretty decent

hmm just read the notes about it:

"the Haltech also allows speed limit cancellation", that's not true as for a JPM model and don't think it does it for the UK either *can't confirm this. Might be released in another firmware release though.

Looked at those figures seem pretty modest increase in HP too... Think I need to go for a visit

New loom in and so far so good

 

we've got a polished Cosworth ready to go !

cuánto?

Late update, Still having some issues with the Haltech system... Have disconnected it now and waiting for a new loom from the US

 

Had to take of the pure plenum spacer, had problems with the bolts unscrewing themselves so accidently overtightened one of them and it snapped right off. After opening to have a look the plastic washer/spacers where crumpled to sheit. Looking at either fixing it up or going for a complete replacement plenum and after market strutbar...

 

Will keep u's posted, nothing worse then loosing 50+ hp

Buy a Torque wrench it will save you a fortune if your playing diy mechanics good luck with the repair

+1 - never try and do anything by hand when it comes to torque! You just cant judge it. From what I remember the plenum bolts dont need to be dont up more than hand tight as they heat cycling somehow keeps them tight. Not too sure other than my torque wrench didnt go down low enough, so let Phils lot do it

used the correct torque on the wrench but had to tighten the bolts every now and then... micky mouse bolts... thats what I recon, think I'll sell that off and get myself a 4*times more expensive one

IIRC it was posted that there was just a couple of BHP gain. The biggest disappointment was the build quality of the final items. The original looked stunning, but the production items really did not look the part.

mmm that sounds a bit sheit... well waiting for my low quote

Wasnt there a post by TDi where they said they'd seen gains of only a few BHP? I seem to remember them eventually saying that they didnt think it was worth it. And also that the plenum is more useful for FI applications where it gets those bigger increases? I could be just imagining it, but I'm sure thats what they said.

 

andlid: As Zedrush said, its nothing against you, but we have been around a while and know what mods give what gains. If someone comes along with something new with gains we havent seen before then we are sceptical. Its nothing against you personally, just that the gains are more than we expect. Hence my comment on the dyno they used. If I came one saying I've just had my car reflashed and am getting +50BHP from a filter and plenum spacer, would you beleive me? I wouldnt beleive myself

Sure my tuner didn't believe it either!

hmm thats real bad if they say it like that, again if I went out and bought it and did a pre dyno and an after dyno it would not be believed in.. since I'm not a member for very long here and not on a proven dyno

 

The words in bold has nothing to do with the fact of whether its believable or not. We are not a fraternity its an open forum and treat everyone equally, hence why its free to be a member, cos its open to all. And all opinions are taken in to considerations whether you are new or old, we are all equal, except Louis who suffers from hiding in the closet and Sarnie who has little big man syndrome

 

If you buy because of its looks and for name sake to have cosworth under your bonnet then good on ya. Its a shame that the person previously who was selling claimed and estimated output without one shred of evidence to back it up. The majority of people would like some evidence into the claimed 24bhp increase in order to entice them into a sale. But for someone to turn around and say well buy it first then see for yourself, is not the kind of truth or dare game most of us wish to play especially at that price.

 

By all means if you do a dyno test on this and post it on here, Im sure all of us would be interested to see the gains if any and can make our decision from there.

(at the bold statement point)

Also if this person tried selling it saying 24hp, put the buck where the mouth is. If I was 100% sure that a car (std) would get to 24hp -+ 7 with the kit. I'd offer money back if it didn't...

Just as a quick hunch I'd say it would give about 10-15 hp, we will just have to wait and see

(not sure it will be sooner, just blew the engine on one of my bikes... )

can you get replacement 'bushings' for these? Heard that Cusco aren't the best dealing with if you need spare's later on... anyone else had any experience with this?

+1 Thanks Steve, was looking into that myself with my JDM

Would go (more then likely will myself) FI just to have a few more HP under the hood wouldn't get it to be able to drive faster during a twistie track / road etc. But for cruising along in motorway speed and just be able to floor it and shoot off would be nice.... wolf in... type of thing.

(trying to find any other reasons to go FI but can't)

Why don't you just go out and get a lock bolt set (the ones you replace one of the standard ones with a lock one?)

i know for a fact.... (last year around this time TDI dyno run...had about 7 Z's run there ranging from 276-309bhp) all Z's have 12-15% loss from flywheel to whp readings.

 

IMO..best figures for tuning are WHP figures...my 276bhp car made 243.5whp, 309bhp car made 276whp....

 

working whp figures back and assuming a loss% just causes the whole reading to vary dyno to dyno...

 

for best result tune to whp figures...and TDI was using some kind of dyno that attached to the rear hubs....we even had 2 FI cars running on that day. So in short...forget flywheel figures unless you want to strip your car out and run your engine on a flywheel dyno ....

also the other thing to say it's all that matters what actually goes into the ground

delivery cost to IRE? (REP)

hmm thats real bad if they say it like that, again if I went out and bought it and did a pre dyno and an after dyno it would not be believed in.. since I'm not a member for very long here and not on a proven dyno

j/k, anyway I think I MIGHT depending on what quotes I'm getting on the plenum go ahead in the new year and replace the pure plenum spacer... (will be up for grabs... ) Might ask the guy pingu2 is using for a quote seem to be a lot more competivite prices then I get over here...

makes more sense then

 

just as a basis for comparison, assuming a 15% loss through transmission (should be about right), I would be around 368 hp at the crank. Not sure how hp equates to bhp though

 

Now I'm confused... are they not really the same?

 

 

(think it's 17% btw)....

 

Next time I'll ask to get it into Kw

 

Tried to figure it out but got even more confused (bhp vs hp) so it's goodnight for me

 

whp = wheel horsepower, so the power the car makes at the tires as measured on a chassis dyno

 

HP and BHP, are power measured at the crank. Only really possible to get an approximate unless you have the engine connected to an engine dyno

 

15%, 17%....one never will really be able to tell, but I use 15% - I'd rather err on the side of caution when approximating crank hp

yeah but you got the DIN HP and SAE HP...

265 whp is inordinately high actually for a stock baseline. Here in the US, depending on the type dyno used and the location, it ranges from about 210 whp to around 230 who, for 2003-2006 models

 

so, assuming your baseline is a given % higher than the normally "accepted" #'s for the Zed, your car is in the 270 range, which for intake/exhaust bolt ons and a tune, is spot on where it should be

265 is on the flywheel...

That you're not as well known and the dyno you used wasn't proven?

 

 

I dunno, just a stab in the dark.

andlid: sorry but the Zed has been out for years and its pretty much proven that gains arent that easy to come by from what I've seen. I'm not saying you're lying but I havent seen numbers that high before so as you can appreciate I would like to see results from a member that has been around longer and on a dyno that is trusted. Put yourself in our shoes, you've been around a while and not seen these kinds of numbers, then some new member pipes up about how they got such good results from the ECU and tune. What would you think? I'm hoping that its all good and then I can get one

 

PS See the guys whos got 470BHP, and see what I mean

lol yeah I know what you mean ... Well all I can say is whats on the paper and whats in the car (if someone didnt hide a single turbo down there somewhere) the standard baseline on 265 is quite low though? (same dyno) for arguments sake I can say that the tuner I go to the lads that want 470 out of their Glanza need not apply. IT's a no bullshit dyno. Had my altezza down there and got gobsmacked at the low HP's it produced and some of the other lads down there where not to impressed either one reason I said to hell with 2.0l here we go 3.5

I'd say it's hard with all these different dynos etc. What I think in my own head is that you start with a baseline at the dyno and keep yourself to that dyno and it's YOUR numbers and you can see if what you are doing is actually gaining HP or not... a finger of salt is always needed. My tuner was actually happily suprised at the gains he saw, even with the basemap it was giving 300bhp, would be nice to see what it does now when I don't have the plenum in it anymore.

Anyhow point taken!

If you really want to you can all come over next summer and have a go

What is a proven dyno btw?

will do - its going in next monday
