The 907 Lotus engine uses a forged crank except for in some early Jensen.Links to other MegaSquirt Forums: MSefi, MicroSquirt, MSgpio, MS Success Stories, MS User Groups, MSextraThe Mk 62's 904 engine was a development mule for the 907, and was a composite of a Vauxhall 2 litre iron-block assembly, a Lotus-spec'd, longer stroke crank and a Lotus prototype cylinder head. The Kent based Fords as used in the Lotus Twin Cam all used cast cranks as stock. The engine is inclined at an angle of 45 deg. The Lotus 907 Engine as it has come to be known has been used in many Lotus's as well as other vehicle, its was developed at the beginning of the 70's based around the dimensions of a Vauxhall engine but with an alloy block, head and sump, with cast iron wet liners.

In a properly prepaired engine, should be doable. More stroke would make usable torque for better transition to boost range. I suspect the weakest part is the cast crank.

Feel free to search the forums for information, facts, and overview.While the R&D forum traffic has slowed in recent years, this is not at all a reflection of Megasquirt users, which continue to grow year after year. To reflect this the support structure has also changed to meet the needs of MegaSquirt Users.Moving forward, the R&D forums for MegaSquirt project are in a read-only mode - no new forum posts are accepted.However the forums will remain available for view, they still contain a wealth of information on how MegaSquirt works, how it is installed and used. The MS project has transformed itself from a simple R&D project into a full-featured mature engine control system. This should motivate a Jensen GT, rather well.The MegaSquirt Project has experienced explosive growth other the years, with hundreds of new MS installations occurring every week - a phenomenal success! MegaSquirt has been successfully used in all aspects of Internal Combustion engine applications including R&D, Industry, Race, and Research.

For those who are not aware, this is the 2.0L Lotus 907 motor that in US trim had twin sidedraft 1.75' Zenith-Stromberg carbs. Finally, for product selection assistance, all of the MegaSquirt vendors are there to help you select a system, along with all of the required pieces to make it complete.Here is a list of active MegaSquirt forums:MegaSquirt: Megasquirt/MS Extra Engine Management Owner's Club: MegaSquirt Addicts: TunerStudio MS: MS3Pro Dragracers: Supplier list for MegaSquirt products:We thank all of you for the tremendous support for MegaSquirt which has made this an extremely successful project!I fired up my 1973 Jensen-Healey for the first time this evening running port injection with EDIS crank fired ignition. For those not on Facebook the msextra forums is another place for product support.

I am running multi-orifice high-Z injectors from a Dodge Neon. I had fuel injector bungs welded into the manifold at a point where the injector squirts down into the intake port and the back of the intake valve. I have adapter plates to bolt them to the original ZS manifold in place of the carbs.

Its purpose would be to adjust fuelling as a function of inlet air temp. Just see if you have a 'MAT fuel compensation' menu somewhere. They are all in a photo album on photobucket.comStevenD57 wrote:When you say the MS1 has issues with IAT can you point me towards some information about that?I still have to figure out how to do some tuning.Maybe things have changed in the mean time. I also need to add some sort of idle air control system as well.BTW, if anyone is interested I have photos of the various bits and the final installation.

Set up your AFR table, buy Tunerstudio, go drive the car and let VE Analyze do the tuning for you. 9&p=202952Tuning fuel is VERY easy. MS1 (and MS2 defaults) took too much fuel away.Perhaps also look at this. IAT very high means air less dense means less fuel. Many guys were complaining about lean running after a heat soak.

I want to try a different WBO2 system to see which AFR value is correct.Overall the car has been very reliable for a first generation system design and first generation wiring harness.The only major modification I have done recently is to relocate the EDIS coil pack and controller from the firewall behind the motor to the driver's side fenderwell next to the motor in an effort to clean up what the install looks like. The only other issue I have is with the WBO2 unit I have displaying a slightly different AFR value on it's display verses what Tuner-Studio says the MS1 ECU is seeing. The EFI has been working very reliably except for a problem I had in Nevada with rust from the old gas tank clogging up the low pressure filter on the inlet side of the external high pressure fuel pump. 2011 and I recently completed a road trip from Phoenix AZ to Olympia WA and then down to Sacramento CA and back up to Olympia WA. If its a high compression engine you could advance timing until she pings and then retard by, say, 4 degrees - crude but close.I have been driving my 1974 Jensen-Healey with the MS1 EFI since Jan.

That car is still running 45DHLA Dellortos until I get a chance to work on switching the fuel system to the same EFI manifold design.
