Hi, I think the Pro Ram is what I'm looking for, as I have a 350 Chevy in a lightweight AC Cobra. Is it worth spending the extra money for the Thruster ECU etc??You are correct, a lightweight AC Cobra doesn't require much low RPM torque.

The pro model required a USB plugin key, to get to the 'pro' version'. More money, and was suseptable to damage, if you had to move the laptop.I did like the PnP ignition. I used the Dual Sync dist to get the sequential signal.In the USA, the FAST seems to be the more popular.Another is the Big Stuff 3. I've not used it, but those that have like it's many features.All 3 units have data logging capabilities.just my $.02.ChuckHotrodding and dragracing since 1955.Injector inspector, and certifiable EFI nut.Back to 55, again, for the 6th time. Thanks for your help, does the Pro-Ram complete injection kit p/n 77142 come with a GEN 7 control unit that fires sequential??This is where things get confusing with the Accel DFI kits.

The Calmap software and firmware revisions 4.0 & higher are Gen 7+, capable of sequential EFI.The firmware versions 3.2 & lower are Gen 7. I don't think these older versions are capable of sequential EFI until you upgrade the firmware, so the answer is 'not yet'.At this point, you know as much as I do and you should give Accel a call (unless someone else has more info).May God's Grace Bless You'78 BRONCO: 508' stroker, TFS heads, Dominator MPFI & DIS, A/C, Lentech Strip Terminator AOD, 3:1 Atlas II, modified Dana 44/60-lockers-4.10s, hydroboost/4-disc brakes, ram-assist/heim joint steering, 4' lift, 35' tires. The Accel/DFI Thruster is only the engine management system but with more features than the GEN 7 ECU:The Accel/DFI Pro-Ram is for high RPM use (single plane intake manifold):Are you sure you shouldn't be looking at their Street Ram?Danny, Actually the Thruster is a lower cost version of the Gen VII DFI ECU. It is programed to have a subset of it's capability. It is probably adequate for most general applications. It was released to provide a more affordable option vs the Accel Gen VII and the Fast XFI. I opted for the Accel Gen VII on my RamJet 502 replacing the MEFI 3.
It is like having a whole new engine. The Gen VII comes with the Sportsman Key which provides all the flexibility needed for a most applications. I purchased the Pro-Key and have even more capability.
More than can be easily explained here.David,The main differences between the Fast XFI and the Gen VII as stated above is that the Fast system has an integrated UEGO function. It also has a slightly larger fuel map table. 16x17 cells vs 16x16. For my intended applications these were the only significant performance differences.At least at the time I purchased, the Accel Gen VII was a significantly lower cost alternative, even when adding the additional $179 LC-1 wide band O2 module. I discounted the extra fuel map cells since they both do a weighted interpolation between cells and the maps could be scalable.I have looked closely at all the afermarket ECU tuning software and I don't buy the statements that the Accel Calmap is not as capable or harder to use. If you truly understand the physics of controlling an engine, the Accel Calmap S/W with the Pro-key is hard to beat.
It also has capability for generating base maps for semi-auto tune which will get you close. I understand that Accel is close to releasing a Gen VIII with more capability like coil on plug. Etc.I updated my RamJet for a little over $1300 including the LC-1 and a GM 502 Knock sensor module. I built my own harness and interface board wanting to get a cleaner more professional setup. I hate those plastic accordion harness shields.BullsharkEdited by Bullshark on 05-26-08 07:46 PM.
Reason for edit: No reason given. 05-28-08 02:33 PM -In response toI just got my Gen7 system dialed in. My complaint with the Accel system was the lack of support. I called the tech line a few times and got voicemail. Webeasy professional 10 support. My calls were never returned. I was able to solve my problems with the help of people like Bullshark and Doug at Herzog Racing.
I fought an issue with timing during cranking. It turned out to be that my MSD distributor wasn't compatible with the Accel system. I replaced it with an Accel dual sync and I'm now a happy camper. Now that I've learned the system, I love it and would recommend it. I just wish there was support like this forum has for the 950!My $.02'70 Vette roadster, 383, Dart Pro 1 heads, Ultradyne cam 250d @.050', Accel Gen 7 EFI, single plane w/port injection, 1200cfm 4 barrel throttle body.
05-29-08 08:21 AM -In response toHi DavidThe ACCEL DFI THRUSTER EFI Engine Management System is an entry level system that is based on the GEN7; that is why it can be upgraded to Pro Version in the future if you so choose. The THRUSTER offers 35 Screens of tune-ability and diagnostics while the Pro version offers 144 screens.The Pro Ram Plug & Play EFI system is a complete EFI system that comes with the THRUSTER EFI electronics. You will still need a distributor, ignition box,coil to get it running.ACCEL DFI has recently released an Engine Builder Kitwhich comes with everything you will need to convert to EFI including all of the ignition components and the wideband O2 / Datalogger.Take a look at capabilities below of the THRUSTER EFI SYSTEM. Very imp-ressive for under $1000.00 with a narrow band and under $1400.00.Any questions?.
THRUSTER EFI: Is an entry level EFI system for the masses.System Capability: Whether you have a 200HP or a 1200 HP engine, Naturally Aspirated, Nitrous, Turbo or Supercharged, the system is capable of running it.Real Time Programming: Using a Laptop, you can fully program the ECU in real time. All changes happen instantly.O2 Sensors: The system uses a Narrow Band or Wide Band O2 Sensor.Closed Loop Operations: Utilizing the Wide Band O2 in closed loop, You command what Air/Fuel Ratio you want and the wide band will auto correct up to + or - 25% (A great tool for tuning especially when using Nitrous, Turbo or Supercharged applications).Volumetric Efficiency: The System is Volumetric Efficiency based just like an OEM. This type of system makes an 800HP small block start and run like a stocker.Target Injector Timing: The system allows you to target when the injectors fire in relation to crank rotation. This can enhance drive-ability and can increase horsepower by as mush as 10%. No other system offers this.Power Enrichment: Power Enrichment Mode offers a way for you to switch on the fly, to an alternate Target Air-to-Fuel Ratio table.
This provides a means of calibrating the ECM for both fuel economy and performance at the same time. E85 Capability: The System can be configured to switch on the fly from gasoline to E85 fuel.Injector capability: The system is capable of running High or Low Impedance injectors in Sequential or Batch Fire.Individual Cylinder Control: The System is capable controlling the fueling of each cylinder individually at all RPM and Load parameters. Actually, If we are going to go around handing out credit where credit is due, it should be mentioned that guys were around in the very early eighties building much higher quality systems than anything Mr. Hi DavidThe ACCEL DFI THRUSTER EFI Engine Management System is an entry level system that is based on the GEN7; that is why it can be upgraded to Pro Version in the future if you so choose.

Engine builder kit includes all the above plus the Dual Sync Distributor, DFI 6 A Digital Ignition CD Module, DFI E-Core Coil and DFI Wide Band O2/Data Logger.ACCEL DFI has a network of EMICs (Engine Management Installation Centers).
You can locate them on our websiteor you can email us direct at for a dealer that we might recommend that is familiar with the application that your working with.Good luck. 06-23-08 08:42 PM -In response toI have two Edelbrock Pro Flo RPM EFI units and love them. The first one I bought just over 2 years ago.
Calmap Gen 7 Software
Edelbrock gave me all the help I needed to tune it, plus I didn't need a laptop to set it up. The first one I had on a 454 BBC that was around 475HP @ 500TQ.
The second one I just got 3 months ago, and it went on a 519cu.' BBC stroker 560HP @ 5000RPM, 650TQ @ 3700RPM,dyno run, and it works just as good.

The new Edelbrock I bought can be hooked up to your laptop for tuning or you can use the hand set by itself.I hope you can find one that works for your engine. 06-27-08 04:42 PM -In response toSo there is no correlation to crank or cam position when a batch fires?I was under the impression that batch A fired say at Number 1 intake stroke, and 8,4 and 3 fired at the same time, the batch B fired at #6 intake and 5, 7 and 2 fired at that time also, so at least some semblance of efficency was achieved, if the batches just fire at any old place, it isn't much better than a piddle valve type injector system that runs all the time.
