Thanks to Phil who popped down today with his modified Megasquirt and laptop.

After much messing, we tested the Rev limiter :mrgreen:



I’ve asked Ian to look at the youtube problem - just click the link for now.

Edit - Ian has fixed it. Slightly different address format to what we previously used - press quote to see the code.

Numbers won’t be high as this is a Mundano 1.8 as opposed to the 2.0 litre with I wrecked. Hopefully get some mapping done before the rolling road.

So after lots of setbacks, I finally got it to Northampton Motorsport rolling road for mapping and weighing. The standard 1800 should produce 115 BHP and this one made 120.9 with 126.4 lbft torque. With vernier pulleys I might have got a bit more but as the weight was up a little (858Kg without me as opposed to 846 last year) I have almost exactly the same handicap figure but more torque and the engine feels like it winds up quicker.

I think the real world gain will be massive as the twin carb CVH bogged a lot in places. Should be mega in the wet now!

Dads coupe has less power and lower peak rpm then black beast had but we can run a higher diff ratio due to the low down torque and wide power band so speed achievable in each gear isn’t affected.

Real world comparison was Prescott hairpin used to be clutch kicking in first, whereas we can pull clean in second with the stock BOB.

Great work Jim, as James says, I'm sure the combo of efi , decent mapping and a revvier motor will pay dividends in times with same handicap.

Spent almost all day checking the wiring and came to the conclusion that the injector drivers are toast. I have fuel pressure and can jury rig a supply to make the injectors fire, I have continuity from each injector wire back to the ECU and the tunerstudio says it’s trying to fire them - but still no fuel :(
Just as a post mortem on this aspect - not only were most of the injector circuit driver components toasted to oblivion, so was the driver chip which runs them as well as the track on the PCB that feeds it with a supply voltage in the first place. Advantage of an early Megasquirt is it’s all low value discrete components so several hours with a soldering iron and it was all replaced for the cost of a round of drinks :D

By the looks of it, it wasn’t the first time half of the bits had been replaced either..

Just annoying (to put it mildly) that a “working” unit (as bought) was absolutely goosed :evil: so a lot of time was wasted in the first place chasing shadows.

Very glad it held up for the whole of the session though.. :wink:

Awesome! glad its all come together now. Did Troy map it? he was great when we took mine up there.

This is going to be a great car on track - as JC says, the switch to EFI will make a massive difference; one of the very noticeable things after converting mine was the absence of any coughing and spluttering when you hoof it out of certain bends - it just picks up and goes.

I took G97 for its MOT last week (which it passed) but it threw up a problem with the throttle position pickup. Turned out to be a broken wire, so we rewired it along with a new 37 pin plug on the Megasquirt and a couple of inline plugs on the loom to make any future trouble shooting a bit easier.

Sorry nick, I missed this - yes it was Troy, he was great once he refreshed his rusty Megasquirt memory :D

First 2 events of the season were Prescott and Harewood (having missed Gurston and Wiscombe so totally re-organised calendar) and the car was great - 2 seconds up on last years Prescott times and 4 seconds up at Harewood. Next is Castle Combe in July which doesn’t really suit the car (but we have to do at least one circuit amongst the hills, so this is closest). Also going to Shelsey this year which I’ve wanted to drive for years but never got round to. Another Harewood after Curbs and a late Combe will just be the 8 events I need.
