MG Sports Cars

Good one, Rob.
The strobe effect will lull the competition to sleep

Huh. Not quite what I had in mind but it does have a sort of playschool appeal.

Jim

A Robo dizzy!

Yep. Mr. Roboto.

Actually, a cam sensor for the BOPR with the LS engine controller. The 3rd one I've made, all different designs. Come to the EFI tech session at the BritishV8 meet to see them all plus much more.

Jim

The wiring for the GM EFI is now all done. Needs some checks done and a bit of program changes, mostly to accommodate the firing order plus some general tune up and maintenance. Should be firing it up in another week or two I think.

Jim

Looking forward to the start up report Jim!

I'm also looking forward to that Jim!

Fittings for the coolant drains came in today, that's the last thing I think, before the programming work. Soon I will have no more excuses. I'm fitting 90 degree 1/8" NPT street "L"s to the block then pipe nipples, then valves. That way it will be easy and convenient to drain the block into a bucket instead of all over the bottom of the car and widely distributed on the floor.

Rolled the car off the lift yesterday. I've been in negotiations with a couple of tuners over the last week concerning the initial tune. Issues about running boost and changing the firing order need to be resolved. One is clueless about the firing order and the other wants to do a custom OS and add tables for the boost, meaning being married to EFILive as a tuning suite instead of freeware, which I'd rather avoid. But it does have more capability. They run separate licenses for cars though so the issue is avoiding multiple license charges if, say I wanted to tune with my laptop, desktop, or android phone.

Looks like HPTuners is going to get the nod. One of the more expensive options, and it costs $100/ECM to use plus $300 for the adapter (software is a free download) but it is the most refined tuning suite I've come across so far, seems pretty intuitive and easy to use for the most part, comes with a library of stock and custom tunes, has an active user forum which seems to have a friendly culture, and probably the single most persuasive item, has real time tuning (RTT) which I came to rely on with MS. So it fits my tuning methodology. It also has easily understood and used histograms which you cut and paste into your tuning tables to make adjustments easier. Lastly there are a lot of u-tube videos, some of which are professional grade instructionals. So I expect I will make that purchase today.

The time I have spent so far just getting to this point would pay that cost many times over.

Jim

Today (technically yesterday now) was a day of success. Once again I have pulled off a coup that nobody else has ever done. It was a long hard challenge, far beyond what I expected, but now that it's done I feel that the results are worth it. Let me just say that I had a lot of help along the way, and all of you who did have my thanks.

So, without further adooo, the Buick 340 now lives under GM control via the junkyard P01 ECM from a '01 Silverado programmed with an operating system that was from an '02 Camaro courtesy of my friends at GearheadEfi.com/forum with a 2 bar mod from HPTuners and parts of a tune from a guy I don't even know called Country Boy and other sources plus a great many U-tube videos. It has COP, all the GM sensors and now probably runs better than it ever did before, even after only one day of tuning efforts. That will only get better.

So I think this probably ends this 340 thread. The goal has been achieved. Sure there is more to be done to the car, but there always is and those can be posted elsewhere.

Were I to start over would I go this route? No, but about the only thing I would do differently would be to build the engine based on the 300 block instead of the 340 and use the TAPerformance heads. In fact, that engine including heads is at the machine shop today. I also still have the 8 speed and an upgrade to the GM E67 Controller and TCM from a 2014-2016 Cadillac might find it's way into the car sometime in the future. Other plans include completion of the AC system along with a new dashboard design, completion of the active wing controls, and possibly a new front suspension design with proper onboard height control. But for now I'm just going to drive it.

Fantastic!

Jim, Cool! Any pics of the COP's.

Only thing I have right now:
