Rolling road day with a difference.

[Ab Shocks]

Rather than all meeting up for a willy waving day, I have asked Atspeed at Rayleigh to orgasise a day to show what can be achieved on std road cars by optomising fueling and timing on a sample car and testing as many others as possible.
They have offered to do this on Sat 4th September and I think it could be an interesting day. I will also drop down to take people out in the Gaz car to show that the hype matches up to reality.

Sign up below if you would be interested in optomising what you have got without FI.

[Matt UK]

I'd be interested in this

[MX-5 Lazza]

Me too

If you're talking about the Hornet fair enough, if you're talking about your SC jobbie, that counts as willy waving and not what I had in mind but you are always welcome anyway Laz.
BTW, I'm on Nutz as well but if you want to help promote it anywhere else, great!

[MX-5 Lazza]

Yes I am talking about Hornet (though if I can get one of the other guys to take Hornet I'll bring my car anyway )

How do you propose they adjust fueling on a standard car?

Its a copy of the Bosch system with a clock type mechanism where the spring wears and you can move the fueling up and down the range to get an average fueling for power or ecomomy. Quite often the 1.6L is running very lean or very rich and goes down on power to 100bhp, if you add into this the fact that the timing marks are often 4 degrees out, it is possible to move back to the 115bhp that the car was intended to produce by just adjusting average fueling and optomising timing

I'd be very interested in this!

Cant do 4th September but i would be interested if another one is organised in the future.

Ah I see I was thinking of my 1.8 which isn't a flappy type air meter and theres no adjusting fueling on that. Base timing has often been discussed and some claim a move to 12 or even 14 degrees is beneficial in the mid range on 1.6's but again doesn't do anything for the 1.8's.

Watch this space, Piasini have software for the 1.8 and the 2l sport and the 1.8 goes up to 150bhp before improving induction. I'm getting data together for the 2L sport we use in the Mk3 race cars and this will cross over for the 1.8's

[Stevesh]

Which mk 1.8?

150bhp in a Mk1 would be interesting!

+1 Same here

Agreed a quick remap of the oem ecu to 150bhp would be great.

[snotrag]

I think there talking about the 1.8 and 2ltr duratec Mazda/ford engine there.


The mk1 ecu is too stupid to be remappable and even if it were it's pretty slow/unpowerful.

Which is why even on an otherwise stock 1.8 you can get 150 quite easily apparently just by losing the maf and running it off megasquirt. Which I am seriously considering.

Afaik above ~4krpm the stock ecu is about as clever as "put loads of fuel in" and that's that. Hence poor economy too.

Where I'd this rolling road?

[dylan0451]

this is exactly what i was going to have done/looked at by my local RR chap. will def attend if i can make it. i'd be interested also to see if my apparent 137 horses actually exist from a 1600 of whether the operator added some bullst correction factors

[MX-5 Lazza]

137bhp? What's been done to it?

I thnik he's assuming some of this -

Anyway I looked it up - are we talking about rayliegh in Essex? Pity cos thats too far really.

[J-Tuner]

Registering interest if there is some extra grunt to be gained on my totally standard Mk1 1.8 in the future!!

[BCA]

Ab shocks, are you saying there is a potential of 150bhp (up from 130-140bhp) of a mk2 1.8?? Or are you talking about the Duratec in the later mk3 cars?

I hope someone turns up with a standard(or standard-ish) mk2 1.8, I'd love to make an appearance, but my car is hundreds of miles away from the RR and I am in Spain still...
