CXRacing TT Conversion - Electronic Throttle Control Hello people,
Am after some tech advice, I own a Holden Monaro in the UK and am looking at fitting a CXRacing Twin Turbo conversion from the US, my car has the 5.7 GenIII LS1 but has the drive by wire electronic throttle control (8 pin version), I am sure I have read somewhere during my research that forced induction causes problems with this sort of electronic throttle control. I was just wondering if any of you guys have had any experience with similar set-ups? Additionally to this how did you go on with mapping, did you do it yourself with efilive or similar or have it mapped on a rolling road?
Apologies for all the questions - any advice is greatly appreciated!!!
Thanks in advance,
BigG.....

I have no experience with DBW, but if tuning it, dont set for less than a dyno tune, preferably road tune for more load, as I hear ethanol is hard to come by in the UK, if you do encounter problems, you could consider self tuning ecus such as fitech and a methanol water kit to keep things alive longer, as I dont think there are many LS/LQ powerplants on UK junkyards

There is no reason for the stock DBW to give any problems.
And as for tuning methods...less important than the competence of the person doing the tuning and ultimately it will always need checked and finalised on the road anyway

Thanks for the replies guys!
Will be running on stock engine so keeping boost @ supplied level which is 8psi i believe, what size injectors would you recommend i go up to from stock? Additionally to this i have read conflicting stories about the standard fuel pump with some people saying its OK for around 550-600bhp, do you think this will be OK at the boost levels i am planning on or will this also need upgrading?
Thanks again,

With regards to the fuel pump, can I just replace the in tank pump and use the existing lines without modifications? I was looking at the one in the link below.

I'd probably prefer to stick with the bigger brand names, Walbro, Aeromotive, AEM etc etc
Presumably you've been here and spoke to other UK owners to see what routes they've maybe taken ? not sure if username looks familiar or not

I would not be keen on using anything bigger than a 255lph without also upgrading the wiring to the pump, but yes a 340lph is a good pump to use, there must be a dozen different makes knocking about now. Whether they're the same pump or different, who knows. Quantum though ? never heard of them

There will be...
But on your exact vehicle platform ? not so sure.
Monaro is almost same as the Pontiac GTO, depending which year yours is.
As a 5.7 ( almost surprised it has DBW ) your tank is probably under the rear floor ? So different than later cars and the GTO.
Not sure if any US guys will sell fuel pump kits/wiring for your exact model ( although not hard to wire yourself if you've a bit of common sense. )
You could just fire in the 340 and it probably would be ok though, especially if you arent pushing higher fuel pressure than standard.
Some of the Aussie vendors may well offer pnp solutions, they'll definitely have your exact model there. The Aussie LS1 forum tends to be pretty dead though, and not sure which vendors you'd go to there.
Dale at Castle Hill Performance knows his stuff, not sure how much mail order stuff they do though
Locally Monkfish and Walkinshaw are probably the more commonly heard names.
Or Richard Ingram could be worth a shout
This FB page also seems to have a few guys building stuff too, so if looking parts maybe shout there too

Definitely DBW its an 06 plate, its the later small boot version - i believe the tank is behind the back seat?
