Hi everyone,

 

I've recently had my CAVE engine overhauled. Having spent all this money, I'm keen to try and make sure it stays healthy for as long as possible.

 

I've read here and elsewhere that some folks believe a decent stage 1 remap can be beneficial for the long-term health of a CAVE, mainly due to improved fuel delivery (ie. not running as lean under boost, less cylinder starvation). I have aboslutely no interest in chasing BHP, especially not at the expense of engine reliability.

 

Just want to get an idea of your thoughts on this?

 

I'm currently running stock ECU software 9971, NGK SIZR spark plugs, latest revision coil packs and HPFP, no hardware mods. Aside from an occasional blip at idle, it runs beautifully. The DQ200 has also been remapped with TVS Driveability Upgrade software for longevity (unsure if an ECU remap would then warrant another remap of the DSG)?

 

Thanks in advance for any advice/opinion.

 

 

A decent stage 1 map can be great.

The APR Stage 1 was and the REVO was not.

 

So do you have anyone local that can remap that can be trusted. Maybe someone with experience of Twinchargers?

Talk to those at TVS.   They are the people that should know.

 

Had your car had the Breather Mod and Software update early on in life.

You say it is running stock software, is that stock from the factory 2011 & not as was done with the Breather Mod? 

 

?

Did you get the later Oil Spray Jets?

 

Maybe talk with them.

@Ootohere Thank you for your reply.

 

I’ve been looking at the APR remap and also RTMG (who are actually fairly local to me). If either of these would be beneficial in the long run then I’d happily pay the money. As I said, not interested in more power… obviously it’s an outcome of these remaps, but the car is already plenty fast enough for my needs since the overhaul.

 

My car had the cylinder head breather mod done in 2012, and was running version 9970 of the stock ECU software when I got it. I updated this to the latest 9971 version about a year ago, this is the revision that tackled the knock sensitivity and fuelling issues in the original code (mentioned in Lucifers Ultimate Guide).

 

I had CAVD oil spray jets installed when the engine overhaul was done, since they appeared to be the ultimate solution for the twincharger’s oil consumption woes (six months and 5000 miles later it hasn’t needed topping up once).

 

Very pleased with it now, feels like the engine it should have been from factory (there I go jinxing myself again). Just wonder if a remap is the final piece of the puzzle to help ensure some long term reliability…

 

On a side note, do APR insist on remapping the gearbox alongside the ECU? I know some tuners do due to the 250nm torque limit.

 

 

Do APR Dealers even still do remaps on Twinchargers? 

 

RTMG are maybe the best for you to discuss things with 

It appears they still do, I’ll reach out to both and see what they have to say. Thanks for your advice.

Rtmg are the best for maps in my opinion
