CIS to EFI kit

[flat6pilot]

I have a RoW 1980SC and Tony's kit was near flawless.

Love it! Great power and throttle response. Very easy to assemble.

Note: I had the motor out of the car when I did the conversion. I was fixing leaks etc over the winter.

go to Tonys website for price and support is great if you stay with his base kit.

Greetings from Australia



I have spent a wonderful hour reading this thread and was wondering is the kit available in Australia? If so what is the price? Oh and what sort of support is there to iron out any bugs?



Regards

it is the way to go very versatile I went from normally aspirated to turbo and the tuning went along with it with some upgrades.

Hi All,

Without reading through the whole string... How have everyone's experience been with converting the CIS to EFI using this kit? I am fed up with the CIS and a Porsche Shop in Maine tells me this is the way to go!!

Wow just saw the posts were from July

Tony should do a 2009 (or 10) update to this to show changes and where the system is now.

+1

I also think that now that the ITB's from many vendors are more established (PMO, etc) that it would be nice for him to further develop the MS /Sensor /Tuning side of the equation. I have my system mostly constructed on the workbench... But i would pay someone like him to sell me a MS ECU with the base maps, TPS, IAT, CHT etc all set up and turnkey. Would give those who want the ITB look some options that are more DIY and affordable.

I wonder why Richard didn't make the EFI manifolds equal length? Does anyone? Maybe (other than simplicity) there is a reason to stay with the two curved manifolds on the side and a straight one in the middle?

Kit is pretty much unchanged except he doesn't sell a full kit anymore you have to aquire your own fuel reg. and injectors. My opinion is he should update the kit to expand different things going on today. The megasquirt 1 ver. 3 board he is using now supports MSNS extra to give a 12x12 map and also control distributorless ignition the cost of replacements if available to our 30 year old ignitions are getting very expensive and even if you go with MSD ignition in its most versatile form requires the distributor to be locked down to work properly (6al programmable). Just about everyone I have talked to wants to replace the aging equipment with newer stuff to make the motors more eff. I couldn't believe how stable my timing was when I went to EDIS and I realize that its not the best solution out there but it is an improvement over the ignition I had. Your thoughts are welcome. EDIT: I also think Tony's kit is the best starting point for any sort of ful/ignition update that you might do, it is versatile , cost efficent, and easy to modify/tune. support is great and the megasquirt community is almost as good as the pelican group.

I agree.

I have the MS 2, v 3.57. (the newest). It will allow full ignition control by just changing a few jumpers. No soldering needed.

I also use a relay board that eliminates the need to use inline fuses or relays. Less wiring in the engine bay is good.

Changes like this are not only helpful but dont add much cost (my relay board was $80). It also makes MS and the Bitz Kit more attractive when you consistently develop your kit with upgrades and tweaks.

Also, I think long term there will be an issue with reusing CIS components as they are slowly becoming NLA. (Throttle Body, AAR) so coming up with an alternative set up to address Cold Idle would be great. Fix the CHT and IAT issue for good. Back when the Bitz kit was developed the reused CIS parts were readily available. They are virtually all NLA or TOP dollar now.

Think as the industry moves ahead it would be great to see the further development of the kit..

Not meant to be negative. I think Tony's kit is great and very inexpensive. But I do think the landscape is changing.

Still at bitzracing.com and no I dont think it has been upgraded

[JmuRiz]

What's suggested near the $2000 price point, do you think it's possible to upgrade the Bitz kit, or just leave it be?

I'm back and forth daily on the Bitz, carb or ITB EFI choices.

[gsmith660]

The bitz kit is very versatile but if you want real ability for all the new gadgets then you need one of the newer megasquirt ECUs I upgraded my ECU the extra firmware and had to modify the board to control my EDIS ignition and another note is Tony doesn't install all features on his boards so they may lack some features that you may want.

i had no luck getting info thru his web site so i went a different route. got an 3.2 manifold and found am MS expert who has done a few 911's to build my MS setup for me. does the BITZ guy even check this site any more?

Yes he does and he is quite active on his yahoo group if you get one of his kits and modify it at all you wont get much in the way of tech support. His kit is great for the guy that wants to get rid of CIS and is not looking for lots of do dads and drivers for sub systems it is very complete and his tech support is great if you dont modify it. If you install per his guide and use his basic msq file your car will start up and run very well right out of the box the partial kit is complete except for the injectors and the fuel reg. good luck.

no updates here in a while, is this still a common upgrade?

i bought a kit when they first came out and am starting to get back into the project, should i update my MS cpu?

[tbitz]

Hi Folks, this is Tony from BitzRacing.com

Hard to believe it was 10 years ago since this EFI journey was started. I still have my original 911 running the EFI conversion. There were concerns about reliability back then, I guess it's passed the test of time.

The CIS to EFI kit is still available. I no longer include the injectors and FPR. Two reasons for this. One, it costs me more to bring them in, and resell them than the cost of folks just picking them up themselves. So it's cheaper this way. Second, some folks want to install larger, or smaller injectors.

With respect to the kit, it is the same bullet proof design. A couple of reasons for not changing it. Most folks are just tired of CIS problems and want something that works, and the kit serves this need. Not everyone wants the latest technology.

With respect to the MegaSquirt unit, I sell the V3 with MSI CPU. Why? Because this works, and is bulletproof.

Folks that want better CPUs, have multiple options. First is upgrade the firmware to MSnS-Extra which costs nothing. It adds alot of extra functionality, but that comes with more knobs to turn. Some folks aren't computer literate and don't want extra complexity. They just want something that works.

The next step is to pop out the MSI CPU, and install an MSII CPU (available by many resellers) which is a faster CPU and has more features. Again this isn't for everyone.

If folks have any specific questions please feel free to PM me here at Pelican, or send email to INFO at BITZRACING dot COM.

Spring is here (finally), and I took my 911 out of the garage last week. Rested all winter in there, and when I turned the key, it started up right away.

Great to see the Pelican Parts forum going strong after all these years.

Thanks,

Tony

Hi Tony, I'm glad you stopped by and posted. (I'm zekers12 at the yahoo group)

I've had a number of PM's lately asking about your kit since I've installed mine.
I agree with what you're saying. For plug and play and reliability it is a great kit.
My thread with the build and install starts at the bottom of page 4 here and is intermingled from there on:
Finally, back in the game!

[gsmith660]

I agree totally and Tony's kit is completely turn key and run well right out of the box for most cars. It also provides infinite upgrade flexibility as I started with his basic kit and went to Ms extra software to support EDIS and am now at MS 3 to support even more features so I can bump up horsepower and have dual VE tables for E85

[rennch]

Excellent. Definitely on the soon-to-be future upgrades.
