so at the weekend I went to the dyno to try out my latest cam timing (in -5, ex -7) and get my apexi SAFC set up properly.



my work here is done

Qs 3&4 on the manifold boob with 3 teets (:lol:) 1 goes to the map sensor, one goes to the fuel pressure regulator (It varies the fuel pressure with the manifold pressure, ya see, to keep the pressure difference constant) and one is blanked off. i will probably hold the RPM high for 10 mins nooo...

cool cool

What´s left on the MOT list then chris? At the weekend I picked up a magazine with an article about the new MOT regs. It said that there was an amnesty until the first of April, until then you only get an advisory that it will fail next time

should have got a picture of the 'new engine test procedure' really, but I was too busy laughing

ah it´s not as bad as when you try to connect it back up again

I'm not sure those cams are much use to anyone, too little lift for big power and too much duration for sensible running. If you're building an engine to exploit that much duration then a little machining to allow 10-11mm lift would be a no brainer. Maybe I'm wrong. No, you are right! TODA also did...

yup. if the rest of your dash lights up alright, it's the lighter or bulb

yes it should! does the cigarette lighter itself actually work?

might have to come up for a raid at some point mini imoc meet/mk1 strippage anyone?

Also... It's definitely worth addressing the overfuelling. A few years ago I had my stock mk1b remapped by Rich Benton at Powerstation Tewkesbury and he removed the stock overfuelling whilst remapping the fuelling and it does help hold onto power past the peak. My car delivered a fatter torque curve...

Lauren - my dyno on page 2 goes to 8000

tottacrolla, Lauren - did you notice any drivability changes with your modified ECUs?

so, looking at Lauren's dynos, it looks like they they add fuel (and possibly back off ignition advance I wonder) so you lose power with stock or mild cams...

right, enough about hondas on my 4age tuning thread LOL :mrgreen: Lauren, your top end is about the same as mine, so the final power figure is about the same, but you have a peak of torque in the mid range that I don't have! I wonder if that's where the 4-1 comes in..? if so, you should be able to r...

grant - JMR posted the normal and secret ignition maps on my tuning thread here http://www.imoc.co.uk/forums/viewtopic.php?t=131284 This should be a very useful for setting your base timing. With 11:1 compression and those cams you may need to back the timing off a little more than even the secret m...

will be very interesting hopefully they can do an AFR trace.

sure, post up what you need to know.

the tuning continues!! when running aggressive cam timings (with 2 or more degrees of extra overlap) I am getting rough running at low rpms (1-2k). you can't cruise at these very low rpms because it jerks, and the idle adjust screw is no longer enough to sort out the rich fuelling at low rpms/idle....

my current favourite cam timing: in -3 ex -5 This give me a load more low end from about 2.5krpm, I suspect because of the overlap, and the top end is still really good (although not quite as much as when I had the crazy retard). The low end drivability is affected though; I can't really run much mo...

...I'll be very happy indeed if it makes 140bhp. We shall see! I made 133bhp with 264/256 cams, stock timing gears, stock everything else including the tunnel-through-the-boot intake. Oh and a magnex exhaust, which, judging from JAE last weekend, is somewhat quiet! So probably quite restrictive. Ge...

had an awesome JAE, especially liking the banana raping anyone passing our stand in fancy dress, discussions of deep fat fryers and rayman's t'shirts.

oh thanks for the award

nice one!

don't suppose you've got any pictures... (of the car, or the swmbo/hose beast, or the driving instructor, I'm not fussy!)
