For Sale / Miller WAR chip - UK (will ship worldwide)

« on: April 20, 2011, 06:21:12 AM »

Apparently, yes it will! I was going to do some work getting a UK map on to it but never got around to it. It has a US m42 map on there at present.

Hi guys,
As per title, never used. Think they're $350 new, so $275 delivered to the US sound reasonable, pending quotes on couriers!
In the UK, £200 obo will secure it (haven't done currency conversion, just a ballpark).

still sounds great above 7k so that's a 66% increase in post 7k grin factor

above 7k no-one can hear you scream!

Andy, just noticed on 18th may in Argentina they have a public holiday set aside to help you out:
http://en.wikipedia.org/wiki/Public_holidays_in_Argentina

On a more serious note, don't think extra rpm will help the peak power output of yours! And you don't have an extra 500rpm over megasquirt, it had either none (if I built the map from scratch) or 7,3k (if it was based on mine, can't remember what i did when i built si's). So there
Fwiw on standard head, inlet and those cams, you're not going to get peak power above 6,5k. You know that! Look at the shape of the curves you posted and you can see that it's looking really healthy on MS and that fuelling perfectly it's peaking at 6,5k ish.  And "drilled airbox will have helped" - no it won't have, you know that as well as I do!
I'm really impressed at how well it went with megasquirt on, and the power in general that it makes for its spec is well impressive. A solid 155bhp on motronic and 160bhp on squirt is pretty good going for tame cams and 1.9 being the only mods. If I had money to burn I wouldn't mind r/r'ing the 1.9 in mine at the mo - with the higher CR, wilder cams, flowed head, light fly, ported TB etc it would be interesting to see what it does. It certainly seems to go rpetty well at the top, if a bit crap lower down. Sadly it'll come out this wknd though!

lol, how's that a lie? i refuse to change my sig to
1.9 170bhp ish until 2 wks time when its back to 2.1 200bhp 318is. I don't think anyone cares Although actually I quite like that.

Sal's chip = same as megasquirt - behave. I think the AFRs were near perfect on the MS. We should get AFRs off Sal's chip, the old chip I had wasn't any richer iirc, you might be costing yourself a few hp there.

lol you're gonna kill that lovely engine si and i built aren't you?!
Lol yeah yeah, I've driven the inverted billies and offset powerflexes in Dan's except he had 16x7.5" hartges, eibach ARBs and a few other toys yours doesn't. Drove pretty well. And of course been around the 'ring in Tom's car with your suspension and bushes/diff etc!
Sig updated Email coming your way too, you'll like this!

hey andy! Seeing as you've put up no pics, here's one or two from the ring:

The 1.9 on the left, the 2.1 one from the right


2.1 in the middle, 1.9 on the right!

This car has plenty of history and attachment for me, not only because it's the twin of mine, but because I fitted its engine, have been in it crashing on the nurburgring and road tripped it to wales! A special car!

good spot on the sprocket! tom i've got a spare newish sprocket if you're feeling anal and want to sort it, but important one is the exh side for the cam sensor pickup. can drop it by andy's sometime if you want? I take it you bought a new guide rail in the end, I've got one of those kicking about too!

Suspension / Anyone have experience of Nitron shocks?

« on: April 07, 2009, 05:40:45 AM »

Lucky git! I should be at the 'ring at the end of the month, still wrangling over time off work... Plenty to do to the car too, have just finished getting new front wishbones and new e30 m3 lollipops on, done TA bushes on one side not the other yet, put a new timing chain on, got an exhaust rattle and most importantly have to irritatingly do a partial engine rebuild to cure a pretty small but annoying noise from cyl 1. Actually now that I come to think of it, I also need new injectors and idle wobbliness fixed, possibly new driver's engine mount. Gonna be a busy and last minute one as always! Always have my bro's M3 evo as a backup...
Love the fact that on my return it will undoubtedly be nailed again. Last 'ring trip made a right old mess! Ruined an inner balljoint, a rear wheel bearing collapsed (thankfully on the return from London to Bristol, but started getting noisy on the return journey from Germany), also a small end bush on the old engine decided to start tapping away. lol. I had a look at your thread, I take it yours is ready now?

a friend's VX220 has nitron shocks. It's stunning, I've psgrd around the nurburgring in it. was a good deal cheaper than that though, that's some serious money.

Swaps, Turbos, Buildups / ITB's info/projects

« on: March 05, 2009, 02:10:08 AM »

I know this kinda goes against the point of this thread but what advantages does ITB have over just one HUGE one. I'm sure a Huge throttle body and huge plenum will flow just as good as ITBs. Shoot me down:D

There's much more to it than simply the area of the throttles. In brief, one of the most obvious is that the throttles are much closer to the inlet valves, so less 'dead' area and faster throttle response. Also simlarly reduces pulsing on idle, plus cylinders aren't competing for air in a shared plenum - whole idea is independent supply of same amount of air at same velocity and temp - ITBs are potentially better than most single throttle + manifold designs at delivering this. Port length/dia/taper etc can also be tweaked with TBs to suit modified engines.
In reality on the m42 the standard inlet is pretty well designed and on a standardish engine I don't think there's much to be gained from TBs. Having said that, my engine appears to more or less flat line from circa 5,7k rpm to it's 7,3k redline (it makes between 190-200bhp in this range)- I think altering the inlet would help with this. On a standard m42 you don't see this, though - the inlet seems to be very well designed for the displacement/output. I'd be surprised if there was much in terms of power to be gained by doing this on a near-standard car unless running totally loopy cams. I've actually run TBs both on my old 2.1 and on a 1.8/1.9 with reground cams. On the latter two engines (same car) although I didn't have enough time to properly map them and I think it needed longer trumpets , and there wasn't an adequate cold air supply imo (was running trumpets with socks without any additional cold air feed), the car felt no faster on ITBs (and needed no extra fuel on the map either suggesting minimal gains), plus didn't pull quite as well lower down (again think due to poor choice of trumpet length). Bottom line is that there's not a lot wrong with the standard inlet.

It's been a while since I've updated, so thought I'd do a brief catch-up. I've been mainly working on my bro's euro e36 m3 evo of late and leaving the IS alone. Nonetheless after getting the engine more or less run in, I took her onto the rollers for some mapping. The car made really good power, I was really happy, that's 94hp/l without wild cams, ITBs, VVT, a really strong torque curve and a broad power band. Happy days!



There's def plenty more power in there with some tweaks, but I'm in no rush to do any further engine mods at the mo, although later I may. I'm making comparable figures to standard 2.3 S14s on these rollers, the better ones show around the same torque but a bit more power at the top which I believe my engine could achieve with a better inlet.

I still have a rubbish idle, the engine is noisy (suspected chain - will change this wknd probably), uses a bit of oil (I spose this is acceptable given loosish piston-bore clearance) and a leak from timing chain tensioner despite new bolt and washer, otherwise everything seems pretty good. It looks like replacing the intake boot for an 89-76mm pipe might push me over the 200bhp mark, I don't have the inclination to do so though!

A bit o/t, here's a old dirty pic of the car to liven up the post!
