Title: Rev Limter on GTi and R32
Post by: Rich on June 19, 2009, 11:07:07 am: Whats the rev limiter on them ?

On my 1.4 TSi its high reving and cuts out at about 7600rpm

Thought after about 6000rpm it loses its power.

Just interesting to know :smiley:

The super+turbo-charged 1.4 has quite a big turbo for a small engine (to get the biggish bhp figures) so can hold boost until quite high revs. Hence the supercharger to fill the hole at the bottom end.
The 122bhp turbo only TSI has a smaller turbo.

So in basic terms, the super+turbo-charged engine should re-map really well due to the large-ish turbo.
Okay that was maybe a little off topic but hey ho..... :smiley:

Pretty much but the box will still upshift around 6700rpm...

Post by: neg on June 19, 2009, 05:31:13 pm: 1.4TSI remaps to just over the 200bhp mark. I drove a 170bhp version when they first came out and I was quite impressed (was in the Golf GT).

anyway back on topic :wink:

Post by: Rich on June 19, 2009, 06:06:57 pm: Yes - i have 170ps verison.... i got 190bhp on the rollin roads at Superchips meet. Its remapped and using V Power. Wasnt too impressed cause they said 198bhp after remap. Surely if im using V power as well... it should reach 200bhp +

Revo remap claim 205bhp.. and im hoping a bit more when using V Power.

Gonna have it done by them once ive saved up... saving all the money i get this next 2 weeks to help pay for my fitting of new kit :happy2:

I had my remap done by Custom Tuning - thought i'd mention it... i won't be recommending them :angry015: :angry015:

I gotta remember this as the optimal shift point.

Post by: stealthwolf on June 20, 2009, 07:13:35 am: ^^^Does that mean the optimal shift point (in an ED30) is 6000rpm?

It's something I've been meaning to ask but never got round to it. Given that the DD run was done in fourth gear, does this affect the optimal shift point? Or is it the same for each gear?
Title: Re: Rev Limter on GTi and R32
Post by: Jules86 on June 20, 2009, 08:36:54 am: Best bet is to find the max speeds for each gear and then what revs you go to when changing down. The optimal shift point is one which puts you in the power band for the next gear. To late and you will overshoot and to early and you will lag.

You want to be coming in about 4600 going by that graph fo optimal power.

Post by: Hurdy on June 20, 2009, 11:10:21 am: Power mods on the ED30 like the HPFP, intake,exhaust etc all help to increase the power and help shove the peak power higher up the rev range. Mine was still increasing in power at 6542 at S/Chips when they knocked it out of gear for the rundown.
