Some advice please! I'd like to fit an Astra VXR ecu, injectors and amm to my Vxt, these items I already have. My car already has the VXR engine but standard vxt mapping, amm and injectors. As far as I can see the only hurdle is to have the ecu reprogrammed to suit my immobiliser? If so would I need to take the car to Vauxhall dealer? With the other mods my engine has seems like an easy route to 250 - 260 bhp Josh

Not sure but doesn't the Astra VXR ECU need CAN?

May I ask what reason you want to add a VXR ECU to the car for ?

[siztenboots]

don't think you will flow enough cfm to get any benefit from 80mm AMM without improving the whole inlet breathing. stage 2 , assuming you have a decat downpipe and decent exhaust setup, is possible to see 260 on a bog standard LET that will be near the limit of standard LET injectors , I would assume if you have a LEH engine you have LEH fuel rail and injectors 260 would be the limit of the useful range of the LET turbo , with the VXR turbo the next issue is inlet temperatures and you would really struggle with the small intercooler. the VXR engine has the balancer shafts removed by default there might be some confusion here about VX220 VXR and the Astra G VXR bits

Thanks for the replies My spare ecu came with the z20leh Astra VXR engine I fitted to my car but I swapped back to standard vxt management system to avoid issues with the immobiliser. As the Astra VXR is 240 bhp ish I wanted the whole VXR management system reunited with the engine, I have all the bits ecu, fuel rail, injectors, amm etc. Also my car has lots of other upgrades; Dbillas Manifold/Turbo housing, k04 - 26 turbo, EDS inlet, Pro Alloy rad and Chargecooler, extra oil cooler, 3" full Tubular, Astra VXR airbox etc so should stay well inside its comfort zone. I wanted to know if when fitting a new ecu it needs to be programmed to suit the car? [/quote] And regarding the ecu what is CAN?

you will not get the astra vxr ecu to work in the vx220 unless you fit the astra dash/clocks - as thats part of the immobiliser

Oh well - nice full blown remap it is then!

Surely you would want to with your current setup. Your car would see a huge improvement with a stage 4 map (you have the chargecooler and hybrid turbo). Trip to Courtenays/MMG is warranted imo

[flamingcorsa]

fitting the astra ecu will be a right mission and only get your seeing 240-250hp if you can actually get ti to work! or spend 500 notes and pop to courtney and come back with a safe 290-300hp! think u know which makes more sense :-)

[siztenboots]

yep with that spec and the safety margin of good VXR pistons rods, then really you could be looking at near 400 torque and bhp around 360 , if you get the same base map as me.

[joshua]

OK I'm persuaded remap it definitely is Not sure which though - 3 or 4. Put off bit by the erratic delivery people claim with stage 4. I have steel rods but they're not in the car yet and won't be until November. Also anyone know how much torque the standard astra vxr clutch can manage.

The VX220 ECU is Bosch ME 1.5 the Astra ECU with LEH engine is Bosch ME 7.6 They are complete different and this will never work. Jesse

I killed a std clutch running the m32 box at about 290ft/lbs and 289bhp - converted to 4 paddle clutch from helix after and no problems at all - my setup never had an easy life so you may find the clutch upto the job if you give some care out to it - I never The cover is actually very stronge as oe on the M32 setup DG

A quick question: is it possible to run a Vxr220 map in to a standard Ecu (and engine? I only have a downpipe). I know the VXR has a slightly different turbo, but the idea of 20hp more whith a super safe GM map, wich use standard gasoline isn't bad.....

Courtenays will remap your car on what ever fuel you want and their maps have alot of safety left in them.

Your probably better off with a custom map in terms of engine longevity,
as the Astra map is for an engine installed in an Astra engine bay
our engines therefore cannot run the same maps due to different temperature issues
The base vxr map maybe ok as it's not cranked up that far but you might just as well get something designed for the job
