Courtenay stage 1 map fitted today

[darren]

Went to courtenays today and had a stage 1 remap done on the zaf, first john put on the rollers to see wot it was making before the map it made 256.3bhp and 259.4lbft dyno cell ambient temp was 6 degrees.
Then john down loaded the map and did some dyno testing and came out with an end result of 276.8bhp and 279.6lbft.
Wot can i say im well chuffed the drive home was awsome, the drive ability is so much better incorporating the sports button
Would just like to thank john and the guys at courtenays yet again for doing another top job and customer satisfaction is second to none would definately recommend them :D

SPEC
Courtenay panel filter
Courtenay front pipe
Cool runing thermostat
Decat pipe (made by myself)

yes it is running a decat pipe and running fine even though it has been said on anouther post this is not possible without having a custom map :roll:

Nice one.

Question i saw that alex_c made almost the same power but higher torque on a std map but with a sports cat. your mapped car looks like it now has the same torque as his wouls this be down to the car or are the maps different for Zafira and Astra.

have you got any running problems now with the map and no cat as TMS said it cant be done.

[darren]

nope have no running probs running fine it can be done i have proved this

[Aussie]

have you got any running problems now with the map and no cat as TMS said it cant be done.

TMS didnt state it cant be done what they did say was it may be possibly but would require the ECU to be mapped and the sensor written out of the program but they havent yet done it for a customer so they wasnt sure of the longterm outcome and that was in relation to an astra VXR and a milltek!

nice results.

[darren]

but it dosent need to written out of the ecu mine hasnt been and on my previous astra as well,if he hasnt done 1 yet why comment about it if he hasnt got proof to back it up :?

[Aussie]

it was a question asked regarding the milltek and how susceptible the astra's ecu can be to sesnor faults but he never made an argument about it so i cant see what your issue is unless your looking at stirring up an argument which i hope is not the case!

you have proven it can be done so good on ya, we wait for your long term report .

[darren]

Has anyone got a full de cat exhaust system no there vxr ?

not meaning to stirr up an argument but this was the question asked originally nothing mentioned about a miltek, anyway we will waiting for another year for the exhaust at this rate

[Aussie]

anyway we will waiting for another year for the exhaust at this rate

well thats something you might wont to take up with milltek who manufacture the exhaust and i dont know of any astra VXR owner yet who is currently running a full decat system but i know of one who is running a full decate on their 888 cdti but then thats a different system

[darren]

i was told the system has already been made

[Aussie]

that could be true but then it comes down to how many milltek have made for retail at present or if they have be signed off meeting the required standards to be badged VXR, keep in mind there is a few people involved with the decision.

[darren]

Got fed up so i spoke to miltek this afternoon to get an answer and they said the exhaust has been made got the part numbers and it will be released at the autosport mtorshow in january maybe you can confirm this tms .

[Thorney]

We tested decats on Astra VXR's and they all threw up error codes eventually, they can be written out but seeing as you'll now fail any emissions road side test its not something we can endorse unless its on a race car. We didn't try the Zafira as although it has the same engione it has a deifferent ECU so it maybe that its possible (I'd still be surprised though).

We're releasing all the details on the VXR Zafira and Vecra at Autosport and these will all be available on line for purchase or through the dealership network. Both Vectra and Zafira systems are now in build, we expect stock in January.

So if this the case the TMS why do you sell the Vectra VXR one with no cat we have been here before and all you do is PR bull shyt us just give us a clean honest answer.

Or just admit your not as good as the others on the block

[Thorney]

:shock:

The Astra VXR as n O2 sensor before and after the main cat, ie the sensor takes a reading on exhaust gases *after* the cat which the ECU uses when looking at fueling etc etc. So, if you remove that cat and don't replace it with a race cat the second O2 sensor will take high readings from the exhaust gases and fire up a warning light. THis can be got round with extra mapping but its a pita and not recommended (note, this does NOT mean that its impossible).

The Vectra VXR does *not* have an O2 sensor after the main cat (although it does have one after the front cat - a bit like the Astra precat but larger) so we can get rid of it completely and not cause any ECU issues.

[darren]

thorney i think you need to check your previous post because the zafira and the astra ecu are the same according to epc yet again you are wrong

[darren]

part number 55354334 :lol:

[Phazer]

Let me first say that I'm not siding with anyone here.

ECU hardware is an interesting one. There are 1.2 engines that use the same ECU as a Z20LET, but you'd agree they function differently yes?

Same part number for the physical hardware but different map configuration, different ECU firmware implentation adding/removing features as necessary.

EPC does not list the flashing required per engine type.

[darren]

its the same ecu though isnt it

[Phazer]

In laymens terms they are different, technically they are the same. You wouldn't want to map your Z20LET to run as if it was attached to a 1.2 would you? :wink:

Alex you don't run a Zafira or even a mapped Astra so why this one man crusade against TMS all the time?
Getting kind of boring now?

We're all Vauxhall enthusiasts here, your posts look like they belong on scoobynet?

[Thorney]

Oh I don't mind, if Alex wants to rant at someone better at me on a forum than some poor sod on his commute home 8)

The ECU is the same part number, indeed its common to a lot of vehicles, in fact the same basic unit is common to other manufacturers, however the software and how that software dictates what the engine does is model specific.

[darren]

if ya gonna get technical about it you said they use different ecu

[Thorney]

ah, but what makes an ECU....the hardware or the software that runs it :lol:

[darren]

if you dont mind me asking thorney how many cars have you tested with a decat i have done 9 in total and havnt had 1 play up yet so im finding it hard to understand how you have had so much trouble

[darren]

you should of said software :roll:

[darren]

right back to topic after driving the zaf around for 2 days now cant believe how much better the drivability is around town with the sports button pressed it isnt hard work anymore and has taken the sharpness of it especially when pulling away glad i went for the switchable map

[alex_c]

Alex you don't run a Zafira or even a mapped Astra so why this one man crusade against TMS all the time?
Getting kind of boring now?

Ok sorry not been on for a while as its been crimbo and i've been @ work.

So how do you know i dont have a Zafira i did but thats another question

Can you prove my Astra is not mapped as you did not do it you can not be 100%.

The so called one man crusade against TMS is nothing personal but i am concerned why TMS have to post so much if their product is so much better than every one elses.

all i want is a fair ballance from all tuners to inject an elliment of doubt in to the minds of those brain washed.

[Aussie]

i think this thread has also run its course and so to has all the "my tuner is better than yours"

Time to move on and be happy with what you got!

[darren]

im more than happy :D
