Chip is in and it fires up. Need some time to check all
the wastegate adjustments and brakes. Initial run showed how particular
the ECU seems to be to having the wastegate set correctly. Not
sure if I had it previously set too low or it got re-installed
at too low a setting. Terrible misfire under boost until I increased
the unassisted opening pressure of the wastegate. The Lotus recommendation
is 0.65 bar, mine was 0.55 - 0.60 approx. Looked on the ever helpful
forums and found posts from Marcus at PUK who produced the chips,
suggesting higher is better than lower and above Lotus recomendation
nearer 0.70. If
goes well then I should get a few days driving in before holiday
and track day in July.
Test drive was good but a small pull to the right under braking
and brakes are a little noisy on one side. Examination showed no
real problems so time to re-bleed the system as most likely cause.
Finally finished all the planned work, well almost. Waiting for
chip to be soldered into the memcal by a friend of a friend.
HID's also not fitted yet. There are some pictures in my webshots
Start of a new year and time to prepare the girl for the coming
events. There are a number of items to get fixed in this spring
fix up. The recent MOT highlighted a few issues,
On the list is:
New brake discs all round and pads,
Rear crank seal has been weeping for some time,
Check and paint up suspension,
Clean up engine bay,
Turbo to manifold gasket leaking,
New HID dip lights to fit,
Finally install PUK supplied ECU Chip.
August 30th 2004
On my way around Suffolk on a nice drive to a motor show near Lavenham
when changing gear started to become a problem. Started to
take it easy on the way home when suddenly after exiting a
roundabout no drive to the wheels despite being in gear. RAC
a tow back home.
Got gearbox away from engine in record time about 2.5 hours.
Culprit is the centre of the friction plate has sheared away
Not many updates in the last year. Lots of real life work keeping
me away from fixing various items.
Primary in last few months has been the exhaust manifold
cracked. Due to holiday and expense it had to wait a few months,
then it took the supplier over 7 weeks to get it to me, not
happy at that. Finally all back together plus made a few changes
Painted calipers red, plus the front grill and suspension springs.
Looks good but really need to repaint as it didn't go on as
well as I would like.
On run with some fellow Esprit owners down south and started to
hear some strange noise from passenger rear on way home. On
a test run about 100m from a garage the rear end seemed to
lock up and slide me along road. Luckily only going few mile
an hour. Bolt on rear radius arm had broken, resulting in it
trailing and pulling hand brake cable on. Took month to replace
and repair due to weather and awkward bolts.
With the cold weather coming along decided to finally
look at getting the heating sorted. Turns out that the vacuum pump
in the rear is blowing more than sucking. All the flaps that direct
air through the car, change the temperature and let fresh air
in, are all vacuum controlled and supplied by this pump.
In best Lotus fashion the pump is no longer available direct and
after a few questions on the Yahoo Groups an alternative part number
for AC Delco was brought up. An emissions vacuum pump on a Cadillac
Deville ???? This unfortunately wasn't the right part so sent of
to PNM Engineering to hopefully repair or recondition.
After having some drilled vented front brake discs supplied
by PUK Esprit I have finally fitted them along with Goodridge
hoses and EBC Green stuff pads. This should prevent the brake
fade I experienced on the Midlands Lotus run a few months ago.
As with all things it can feel like I spoke too soon. Coming out
of junction dropped the clutch and took off, noticed a small
clunk when depressing clutch again and couldn't get second.
Parked up and after a few checks and pumping clutch pedal got
feel back and managed to get home.
Thought it was possible that clutch had gone or a slave cylinder
problem. Ordered a full repair kit for slave and master clutch
cylinders and started to take it all apart in the hope it was
one or other. No loss of clutch fluid except a small amount
near slave didn't bode well.
On taking apart master cylinder found that a return spring
had snapped. Replacements are not available on their own and
requires purchase of complete cylinder. Lotus price requires
bank loan so down to local motor factors who where of great
help an managed to find a similar unit for a Triumph TR6. Only
the screw thread for the hydraulics is different. Damn expensive
way to get a spring but cheaper than Lotus part.
Took the gearbox out once more and got all of the seals
repaired. Was going to put the original Lotus box back in but the
case cracked trying to get filler plug out.
After a good run in and finding that the guide tube on the Renault
box was 1/4" too short for the Lotus bell housing (cause of
oil leak), It is performing perfectly. The clutch slip has disappeared
over time and now can give it full throttle with no ill side effects,
well except for wheel spin yeeha!!!
Changed all of the V-belts and Cam-belt whilst working on the car,
plus changed plugs for champion platinum versions.
After the change for the Renault gearbox the car has been fine
for awhile but in the last few weeks I have noticed increasing
clutch slip in higher gears under full throttle. Didn't always
slip and only in higher gears. After adjusting clutch and bleeding
hydraulics still does it. My thoughts are that either the clutch
is damaged or oil contaminated, or the Renault gearbox input
shaft is not aligning with the clutch correctly. Under heavy
loads the splines could be slipping on the clutch plates. Looks
like a gearbox change back to the Lotus box in the next week.
Also ordered a cam belt and other parts to do my own A service
replace the timing belt. Asking around it isn't that difficult just
a little time and attention to detail. Seems silly to £300+
to get a £50 belt fitted. Will write up how it goes ?.
Trimmed up the S300 rubber lib as it looked a bit shark nosed (Details in Modifications)
A couple of pictures add to home page for Vince.
Purchased alloy gear knob and handbrake sleeve for S350. Looks
good with the sills and fitted the gear stick surround supplied
by UKLotusEsprit Yahoo group member.
Spent a bucket on getting a new alarm system fitted, went ok
except somehow they managed to unhitch one of the cable ends
from the gear translator. Was not very pleased when I picked
it up. Their excuse 'the engineer just thought it was difficult
and something only I knew how to do'. yeah right. 20 minutes
a few tools and a jack and it was all back together.
Fitted front rubber lip spoiler from S300. Looks a lot better
than the broken bits of plastic, that should be gold seeing
how much they cost ?
Enjoyable day out with some guys from the Midlands Lotus Owner
The driving was, lets say spirited. Trying to keep up with
all the Elise's really pushed the car, it didn't falter and
held up to the challenge well. Worming a 6'2" wide
car through some of the gaps and small roads had me holding
my breath at times but will not be beaten...
Happy chappy once again the car is back on the road.
To sate my self during the time it was off the road I did a few
repairs and modifications.
SS sill plates, SS sports exhaust.
Disaster Strikes !!!!.
Well it felt that way, out one night around St Ives giving someone
a lift back in the car and letting the car have it's head to a
degree. Go around a couple of round about's and on the exit of
the third, change to second, press the throttle and engine revs
no motion to go with it. Change to third and all is ok. Happened
without a bang, or any noticeable grinding, just no 2nd gear. Not
a happy chappy since the car was running very nicely at the time
and looking forward to some good weekends.
Full story in replace gearbox section, but briefly, took ages to
find someone to look at gearbox, got delayed so eventually did
a lot of the work myself. The car was off the road for about 6
weeks, until end of June. During that time bought the little Fiesta
a run about.
The start of fixing the minor issues with the car and customising
to my taste.
Installed a K&N Air filter, replaced impeller on Charge
Cooler pump, Installed BOV, Ordered Upgraded ECU Chip.
Into Orchard for it's first service, everything basically ok at
this time, but rear brakes needed replacing. The parts costs
where a little much through Orchard as they just quote standard
Lotus RRP. £200 for a set of rear pads seem a little OTT
to me !!!
Placed an order with SJ Sportscars for some rear EBC pads £33,
that's more like it. The rear discs themselves needed to be replaced
as well, not cheap at £220 the pair.
Took a couple of weeks to get the parts and fitted etc. Starting
to get used to the fact that these things will take time on occasion.
All seemed ok until a bolt holding a rear brake caliper in
position sheared, whilst taking Gwyn out for a spin. Luckily
a problem when in reverse but still damn annoying at the time.
Orchard where very helpful, got the car into the workshop that
next morning at 8 on a Saturday. Seems it was a failure in a
brand new bolt not loose etc. All bolts replaced no charge and
made me happy once again.
Purchased car end of march, like a big kid with a new
toy. Very happy with it, it is another goal achieved and certainly
not something I would ever have dreamed about 10 or so years ago.
