Is anybody running the new Accel fuel injection? If so, what do you think about it? I am considering it for the new motor, but would like some feedback before throwing down the money. I am using a Howell TBI setup now. I am happy with it, I am just looking for more tuneability.

I absolutly love my Gen7... Highly recommend it along with the dual sync distributor so you can run in sequential mode...

Its a jam up system, fully and quickly customizable, so much better then the old boxes..

Let me know if you need any specifics.

I am currently running the old Cal Map MultiPoint on my SBC. Now that I'm building a new motor. I wanted a better injection system. I went to my local injection guy Chuck. And he didn't have a whole lot good to say about the Gen VII. Lots of returns and the factory is hard to get a hold of. He steered me towards FAST . He said it is much more user freindly programing. I even tryed to get the same single plane intake, I'm currently using from Accel. We could not even get that from them. He said lately they are real hard to get ahold of and get answers from. I had to have a Brodix HV-1003 modified for fuel injectors.

I have not gotten it up and running yet . Just passing on what he said.

I had the barometric sensor go out in my box, sent a note to tech support, Noah emailed me back within hours, I shipped my box to him, he sent me a loaner so I could make a trip came back in 100% working order.

The Gen 7 is very advanced, there are settings in there you cannot imagine.. I hooked mine up, typed in the engine specs it produced a base volumetric efficency chart and I started her up.. 15 min max. Been tweaking fuel and spark a bit to get it right where a want it...

I have nothing but good to say about the box, best investement I could have made IMO especally running a 415 cubic inch small block at 10:1+ compression and a big roller cam (277/284 .535/.551) The stock ECM just could not be programed to run right with this setup.. the Gen 7 was a piece of cake!

From what I hear the FAST box is a copy of the older calmap box put together by a group of ex Accel engineers..

Tpi don't get butt hurt :flipoff2: I don't own stock in either company so I don't really care. Just passing along the info from a guy that knows alot more about injection, then I'll ever know. I'm in the middle of building a motor close to yours. A 436 SBC Motown block with T1X Brodix heads, Jessel rockers and HV-1003 Manifold, solid roller cam, I can't wait. I own both FAST and Accel. I'll let you know the skinny after I have some time in with the FAST system.

Back to your original question. Buy with confidence!
If the new Gen VII is better then the original CALMAP then you'll love it. The CALMAP is still a great system. Check on E-bay. Lots of systems with software for sale. Even some Gen VII from time to time.

Is there someone you would recommend that I call about ordering a system? I have tried both Summit and Jeg's, with no luck (yeah, I know better). It is going on a 12:1, small intake port (200cc) aluminum head, .500 lift, 230 [email protected] .050" cam, 406 cid. Trying to build a rockcrawling torque monster that still has good HP. Most of the factory based and even most of the aftermarket kits top out at 450 HP. I am hoping for a little more than that. Thanks for your help.

I got mine from Force Fuel Injection and no Jegs and summit do not carry the complete line.. its better to go thru a authorized dealer!

P.S. 12:1 with pump gas and fuel injection is sorta out of the park.. gonna be hard to make that work! Remember EFI uses a o2 sensor, and 02 sensors hate leaded racing fuel!

I also plan on building a 406 Chevy motor soon. Block is ready to go. I plan on using AFR alum heads, forged pistons, forged connecting rods and a new cast crank. Im going with either a 236/242 or 248/254 duration @ .050". Lift will be around .575" I have a real good engine program on the computer that is accurate +/- 5% of the engine power. I plan on being at 500hp and 500ft/lbs. I'm trying to get the compression up above 10.0:1 but with off the shelf pistons I might be stuck at around 9.5:1 with the 68cc heads I want to use.

Right now I'm leaning towards the Holley Projection with the 900cfm carb...good thread here.

Yes, I have learned leaded fuel and O2 sensors don't mix. I have several places around here that sell un-leaded race fuel up to 116 octane. Can you tell me more about the dual sync distributor? I was wanting to run sequential fire, but thought I needed a cam sensor.

Wow.. that 116 unleaded is HIGH Dollar.... didn't want to carry a drum around with me to the trips so I kept mine in the 10:1 range but as long as your aware of the problem go for it..

The dual sync distributor has a Crank and CAM sensor built in, you have to use a spark box with it I have a MSD 6ALN. its just a matter of phasing the distributor and you good to go, took about 20 min to phase mine and I was good to go!

The racing fuel isn't too bad, a little over $5 a gallon. I probably don't use but 10-12 gallons per event. I talked to Robert at Force Fuel Inj today. He really knows his stuff. If anyone else needs help, call him. Thanks to all for your help!

Im thinking about running a Chevy 406, I was reading a article in the June Issue of Super Chevy Magazine.

They have it setup with TPI from Arizona Speed & Marine. Accel ECU, 32lb injects. Streetable Cam 236/243 duration @.050" Lift is 0.552" 416HP @ 5,000rpms / 492ft-lbs TQ @ 3000rpms

Pretty damn impressive torque not many BB can put out that kind of torque at 3,000 RPMs.
