Re the tach, I got these instructions from Richard over at Kampena (where I purchased the kit). Hope someone finds this helpful. Basically, depending on what the tach is set to, just do the opposite ;). Mine was set to 1,2,8 = 0n. I switched it to 8 = On, all others off and it seems to have worked. "Each tacho can be calibrated/programmed manually by setting a combination of eight switches located underneath the grommet on the rear of the gauge. When you remove this grommet and look inside, I expect that you will find that switches 1,2 and 8 are all flicked upwards. If this is the case then could you please switch down both 1 and 2, leaving only switch 8 flicked upwards. Alternatively, if you find only switch 8 flicked upwards, then you will need to flick up switches 1 and 2. "

The flash must be 100% the issue. Thanks for chiming in. For the tach, it reads, but extremely low. (200 rpm when it should be 1100) Worked prior to the flash!

Progress update: - Got the ECU flashed via easimap to the RBTB file Caterham provided, tach and seat heaters no longer functioning. The tach was expected, sounds like i need to reconfigure the DIP switches. As for the seat heaters, they only came on w the previous map when the engine was running...I wonder if there's an expected ECU output signal now that is missing w the new hardware. Could use some tips on this one. - After about 6 hours at the DMV I managed to get my SPCNS sequence number from the DMV, which is a major milestone in CA. I can now drive it around and get the required brake, light, VIN inspections done! - Drove it around the block this morning, first time leaving the house. It's intense! Nothing fell off and I didn't notice any leaks, so far so good. The brakes seem a bit soft and the pedal travels further than I thought so I need to try to re-bleed.

thanks, this is super useful information! I got the battery mount, here are some pics of the progress.

Wrong forum!

I really should have specced the car without a heater, looks so clean! I think I'll not drill the heater valve control for now and drive around a bit to see if the heater core is really needed in addition to the heated seats and then decide.

I'll have these in hand hopefully by the time I return to the US and will report back here with pics!

Here are the final designs I ended up with, being fabricated now. Anyone can order these themselves with the CAD files provided. Sendcutsend.com can turn these around in about a week. The material to specify is 5000 series aluminum, 0.08" thick. Antigravity ATX-12 HD Caterham Base Plate v11.step Antigravity ATX-12-HD Hold Down v9.step

Here's the battery bracket design I've been working on while away from the car. It fits the Antigravity ATX-12HD battery laid down in the factory location. I validated it with a 3d print, seems to work fine. Its a little taller that the factory bracket to clear the ECU better and at the same time eliminate the aluminum shims that are a pain to align under the stock bracket. Plan to get this fabricated over the next week or so after I fine tune the lightening holes. If interested I could make a few for the community, or share the CAD.

So the build process is on hold, due to a planned business trip to Asia. I got to where I wanted prior to leaving. All the body panels are attached and the car is nice and secure under the car cover. There are just a few things left: - ecu remap for RBTB, awaiting responses from Caterham and SBD - headlight wire routing - submarine belts and seat heater wiring - fabricate battery bracket for ATX12 battery - heater control hole - alignment - strategic PPF - registration! So far, I'm 102 hrs in, and prob another 20 or so to get all the little odds and ends cleaned up. If anyone is interested, here is the break down below: While on the plane I had wifi access, so I killed the time by doing some online upgrades shopping! Ordered the following: - battery disconnect - LED headlight upgrade - front nosecone canards - fuel gauge fix module The first two I should have probably just gotten with the kit but was trying to have some restraint, the price was already getting up there. -

This photo is great, no need to take a different one.

Interesting! Next time you have your hood off would you mind taking a photo of the heater cable routing to the valve? Wondering how they routed it from the factory.

For the Watt's link, i had to just refer to the separate instructions and find all the hardware. Pretty straightforward after that. Re the RBTB...I finally got them on. Had an issue where it appears the aft black end plate on the RBTB where the TPS attaches was clocked wrong. Ended up breaking a TPS sensor. Got it reclocked and now seems fine. Car fires up and runs, but seems super rich...guessing this is the confirmation that I have the wrong map. Does anyone know if a standard Tactrix cable can be used in place of the easimap cable? Attached is a video of the start and idle from this morning IMG_2337 2.mov

I sort of knew what to expect given the different blogs. I must say the most frustrating aspect has been installing the diff. Due to a few real and perceived parts shorts I skipped around in the manual a bit and thus had do revisit a few steps. Only to find the missing hardware was in some obscure unmarked bag found later. In the end it appears that I was only missing the following: 1. cushioned clamps of the right size for the bottom of the dry sump tank 2. scratched up lower control arm that Kampena motors got a replacement for 3. self tapping screws for the indicator to pod mounting 4. 1 bell housing to engine mounting bolt that was 10mm too short 5. cotter pin for hand brake pulley surprises 1. tech support needed for watts link 2. water temp probe wires needed to be extended 3. steering wheel not drilled 4. kit comes w LED rear lights (and I bought a set separately to upgrade) 5. fuse box cover seems terrible 6. seat mounting hardware looks cobbled together 7. radiator fan presses against 7 logo in nose cone 8. general patience and persuasion needed to fit parts together Some parts of the kit seem really well done and it doesnt look like any expense was spared - dry sump oiling, radiator hardware, etc. Other parts of the kit have been pretty terrible like the seat sliders and battery/battery mount. I'm also not sure how to check what ECU software is loaded. I purchased the roller barrel setup w the kit but have just installed the stock system for now... BTW how are you LHD owners mounting your heater controls? It seems to want to route to the passenger side, but i don't see how you could actually operate it from the drivers side while belted in.

A quick update, the kit finally showed up on 3/3 and I’ve been busy getting it together. Fingers crossed I’ll be able to fire it up tonight! A lot of odds and ends left to tidy up, but moving along pretty well. I’ll post some more pics soon. I have a few mystery hardware items I’ll need help identifying!
