Because you sell simtek? ;)

If I decide to retain OEM ECU and get EcuTek'd, then prior to the map, I will replace the MAF for a replacement brand new "stripe/post-'05" one as a matter of course, for peace of mind.

To that end is it a case of the later, the better? e.g. would a MY08 hatch's one work on a STi 5/6, and be even better?


For c.£100 vs potential £000's/hassle, it's a no-brainer.

Do Import Car Parts stock them?

The Newage and hatch airflow meters are a totally different type to the 99-00MY design. You can use them in a classic but they're not a straight swap - need physical mods to fit, and again, rescaling the maf lookup table in the ECU. If you're sitting there thinking that because we've referred to the "green stripe" sensor as a "post-2005" unit, it was designed for and will fit the newage cars, it won't.

Not quite sure how you're working that out. Replacement Newage MAF/hatch sensors are usually well over twice the price of an MY99-00 unit, so you'd need them to be, on average, at least twice as reliable for such an exchange to make economic sense. In fact you'd need them to be much better than that, and own the car for the several years it would take to shake the costs out before the upside actually existed.

And that's assuming that the newage sensors are perfectly reliable, which they're not - they still occasionally fail. And on that score I doubt anyone's run any surveys on the comparative reliability of the green stripe vs newage sensor either.

Given that you're thinking of moving to an aftermarket ECU at some point, if you are going to replace your current airflow meter prior-to, the only sensible option appears to be a new green stripe. Although, as I think I've said elsewhere, if you are thinking of going Simtek in the medium term, I can't argue with the logic of those who've already suggested you do so sooner rather than later.


99-00 part, and, for price comparison, newage part

Os sorry, I got the wrong end of the stick...

I thought that the "stripe/p2006>on" MAF was a New Age design (Hawkeye) that happened to fit the MY99/00 and worked straight out the box, as it were.

But what you're saying is that it's still a MY99/00 - just that it was manufactured by FHI from 2006 onwards as a upgraded part designed for the MY99/00, and happens to be more reliable than the original pre-2006 manufactured MY99/00 ones? Is this right?

So original MY99/00 "green dot" = c.£100?

Upgraded MY99/00 "stripe/2006>on" = c.£200?

Those links are taking ages to load on my laptop - problem with internet. So apologies if they'll actually answer my questions. ;)

Correct. And it has superceded the earlier designs in the spares system.

No, no dot/green dot sensors = no longer available new.

No, green stripe sensor = c. £100, newage sensor = c.£200

Got it! :)

Great that the replacement MY99/00 "stripe/2006>" one is still c.£100! This is the point I was trying to make about replacing my existing one of unknown condition for a brand new one vs running the risk re engine detting due to my existing one's failure, etc. - as suggested by yourself! - for £100.

It was my confusion mentioning (wrongly!) "...New Age MAF..." - therefore which would have been c.£200 - that subsequently "confused" you re. your reply to that question. ;)

So by "default", the one in the link below is the "stripe/2006>" one that's a direct replacement for a MY99/00 car:-

Finally, he gets it! ;)

LOL. Don't be (too) harsh. :D

It was ultimetely the "...post-2006" thing that threw the whole thing into confusion for me.

As they say, knowledge is power. :D

:rolleyes:

BTW, thanks for the mine of knowledge (as always).

You should set up a "Group Buy"... for punters wanting to start threads deliberately targeting Splitaaaazz's advice! lol :D

Interesting read for anther Chocolate MAF owner here.

Is this correct that you can run a newage MAF on a classic ? never heard that before.

The green stripe sensors aren't chocolate, they're pretty good, all things considered.

Of course. Provided you can source a sensor with the correct sort of flow range, and provided you can (get someone with the ability to) rescale the voltage to mass airflow lookup table in the ECU, you can use any sensor you want.

;)

Does anyone know the ballpark area that the STi 5's VF28/440cc/TMIC combo maxes out at, post mapping?

I'm guessing the TMIC is (marginally) the limiting factor out of the 3 and no doubt caps things at c.330bhp ???

Yes, Olly at RCM told me the other day that it is 330bhp (or thereabouts). :)
