My Lotus Elan S2 / 26R Fuel Injection System / Setup

So, I purchased a complete second-hand fuel injection setup this past weekend.  The system will replace my Weber DCOE 40 cabs with a Jenvey throttle body.  The system comprises of the following parts:

Jenvey 45DCOE 45mm bore x 118mm long (TBP45i) (setup instructions) - $563.53
Jenvey Fuel Rail Kit (TBR22) - $95.54 USD
4X Air Horn 45mm x 40(AH45x40) - $132.92 USD
Air-filter back plate (ABB2/0M) - $64.00 USD
Throttle Position Sensor (TP8RH) - $135.00 USD
Coil Pack (Sagem Coil-4) ~ $50.00 USD
ITG Air filter (JC50/65) - $128.95
Fuel Injectors 4x(Ford F5DE-B5A / Bosch Part 0280155715) - $99.96 USD
Fuel Pressure Regulator (Weldon 2040-281-A-120) - $250.00 USD
Crank Position Sensor (Facet 90036) - $38.90
SBD Motorsports Serial type MBE ECU + Mapping Software - MBE 967EB8 - $250.00 USD
Throttle Linkage ~ $100.00
Crank Sensor Bracket ~ $25.00
Crank Pulley and Crank Fire Wheel Fuel Pump ~ $75.00
Wiring Harness ~ $150.00
Plug Wires ~ $65.00

The total would have come to about: $2,223.80 but I purchased it for around $1000.00 including shipping to Denver, CO.  I’m really excited about this.  No more fiddling with the Weber DCOE Carburetors which is quite the relief.  Considering that the altitude in Denver is around 5280 feet above sea level, this system should allow my 1965 Lotus Elan project to take things to the next level.

The mapping software can be found here (Software: mbe easimap 5.5) and requires the old RS232 connector to be used to connect the ECU / MBE unit.  Now with the extinction of the RS232, I’ll likely have to purchase a USB to RS232 Serial converter.  SBDev has issued a note on this if in the event the Baud rate has issues communicating.  “The Baud rate on Easimap 5 automatically varies according to what it is able to communicate at. If you are having a real problem with your USB to serial converter, it is possible within the software to slow the Baud rate right down manually, however, the problem may be that your USB to serial converter is not compatible with your computer. We normally use a Targus or Belkin for our Dell computers, but this doesn’t mean to say that either of these will be suitable for yours. It appears to be that each computer seems to be fussy & you will need to find a converter that suits your own brand.”

I’m really looking forward to the rock solid idle, starting up the first time every time, and the ability to climb up the hill (Vail or Breck at around 12,000 ft.).

 

 

Barnblinker Introduction! Hello World!

Hello, world and welcome to Barnblinker.  So many of you may or may not understand the reason for this new site?  Well, let’s just say this is really my site that I’m willing to share with the rest of the world.  I’m a Software Engineer who has a deep passion for classic cars.  My collection today consists of mainly Porsche’s and Lotus’s.  Although, I have certainly had my run of many other cars.  So, why another blog?  Why more information if many of these cars have already been written about?  Well, the simple answer to that is good luck finding information if you’re in the process of a restoration, just fixing something, etc.  What I’ve realized over the years is that there’s a lot of information locked in the minds of fellow enthusiasts.  Well, this blog is just an attempt to organize the minds of those fellow enthusiasts to make that information more accessible to you.   In any event, I’ll keep posting new articles, findings, and maybe you’ll just see what exactly I’m working on. 🙂
