I am based in West Sussex and need my LS3 GM ECU remapped to pass my impending IVA. If I had more time I would use AB but the logistics are somewhat challenging. Has anyone one here had their GM ECU remapped successfully by a business in the south of England that they could recommend ?

Thanks for the response but forgive my ignorance - are you suggesting purchasing EFI live ?

You don't say why you think it will fail IVA.
If it has the uprated cam in it then I doubt mapping will solve the problem.

slow down pal, if you have the standard 430bhp LS3, and you fit some small cats, it will pass, a mate with his can am, just passed his iva

what ls3 version do have??

Well I was under the impression that it would pass but having spoken to AB yesterday on another matter they advised the it would need to be remapped. Today I contacted the engine supplier and they also advised that the Engine and ecu supplied would not pass IVA. So I guess Steve & Dave the best thing to do is get the car to a garage and have it tested prior to IVA - it's just a real pain getting the car from a-b when it's not road legal. It is the 430 version no uprated cams.

Surely the bog std LS3 should sail through - has it got cats?

Yes has Cats - I thought I had all issues covered, maybe I'm just a control freak and it's something that doesn't sit comfortably with Ultima ownership, I know the build really is never finished!. To give a little background the build has been quite challenging with frequent experiences of one step forward, two back, character building maybe, it certainly has helped me develope the walk away process. So tested the car on public roads for the first time this week and all good apart from one minor issue, now sorted. Then a call from VOSA re my IVA application and after an exchange of views they are happy with my application and proof of newness and tell me to expect a call next week to arrange a date. So there I am, patting myself on the back, only IVA to go after two challenging years and I'm informed it needs to be mapped. So like the car I say to myself, it's gotta have the last laugh, it's so female and is the Tangerine Dream. The logistics of getting the car to AB as previously mentioned are quite challenging for me so thought I'd see what's available down south, hence the original post. In all my dealings with AB and the engine supplier they have been helpful and knowledgable, I have no reason to doubt what either are saying but the previous comments in this thread have made me ...... curious, is that the right word.......
What to do...........rolleyesconfuseddrink

What control unit are you using and which software?

Standard GM ecu - no idea on software - all my IT brainpower was used up sorting the Dash2 install - do you need to know the software version and how will I find that - forgive my ignorance of the dark art.

I'd have thought you would have no problem with emissions on that engine. What about getting a mobile tuner with gas analyser out to your place?

Good idea Dave - sometimes you can't see the wood for the trees ..... I'll get one in and report back

Any ecu will be trying to close loop at lambda 1 so if the sensors and cats are in place then there should be no issue.
The problems come when the uprated cam is used and the closed loop can't cope.

if its a 430, using the gm ecu, it will pass, i had the same engine/ecu in another car and it passed

good luck

No I didn't mean get an efilive tuning setup, just for Richard to map it.

But do as Dave says, get it checked first then mapped if necessary, fingers crossed you won't need to

So just to summarise...Standard 430 (with Cats) and ECU will pass without having to be tuned?

I would simply recommend a trip to the local MOT station to have it tested. Minimal cost compared to mapping.
