Swapping highrise intake for stock

[jedpettigrew]

Hi all I've recently bought a vs calais with a high rise intake and a maffless tune. I need to get rid of the highrise but every place I've called says they can't tune the car to the stock intake because of its mafless tune, so I was thinking of swapping the intake manifold and ecu out for stock ones so I can get some more work done and not worry about not being able to tune it. Every tune shop says they can't help me as soon as I mention the mafless tune, something about they ont have the tech. Don't know a lot about the subject but I'm confident someone on here will know

Easy solution is fit a MAF and buy a mail order tune from someone like Mace. You don't need to swap PCM unless it's not a stock VS one.

That depends on how the wiring for the MAP sensor has been done. I'm not sure if both the MAF and MAP sensor would be wired and work on a MAP conversion.

Would something like this do?

eBay tunes are literal garbage. You need to answer some of the questions that have been asked in your other thread, otherwise everything everybody says is just guessing and we can't help you.

Get a picture of the ECU and the label. Open the ECU and get a picture of the chip. Without a lot of this the only answer that will cover your bases will be for you to get another complete loom and ECU and just use those. TBH it would probably be easier than trying to dick around with the unknown MAP wiring if you're not able to trace stuff out.

Is it a 5l? If so it shouldn't have a MAF as far as I'm aware. I might be wrong and someone might correct me. But VS Calais from memory only had series 2 ECU which was MAP. It was only the series three that had a MAF and if so it's the same software as VT 5l and I think very similar to VT 5.7 LS1.
I may be wrong and you might have a series 3 VS but it's the same PCM as the VT.
My VS is series and uses a MAP.

This tells me the OP most likely has a V6.
