35520- 68 camaro

[LEGENDARY 1]

Sounds like the efi sys is a little more complicated than i would have expected. Just h0w much tuning is required to get the car to run correctly and do you need to be a brainiac to figure it out. I'm looking for something more user friendly than a carburator on a raspy big block ( my wife loves to drive the car and i thought this would be the way to go for drivability and starting)

ANYONE???

It completely depends on the engine setup. We provide base calibrations that are built primarily around Edelbrock components, cams etc. We do the best we can to also provide base cals for stock or mild setups. In the end, there will always be tuning required though. The extent depends on how close your setup is to the one we tuned here.

I have just purchased this system for my 427 chev, and have a few questions:

1. I have a Crane HI 6 TR ignition can I use this, if so do you have a wiring diagram to connect this.

2. I am running a very large mechanical roller cam and Brodix BB2 heads and using a aerospace vacuum pump. What problems do you see with vacuum signals, can I still run the pump. I use it for scavaging and to run the power brakes.

1. I have a Crane HI 6 TR ignition can I use this, if so do you have a wiring diagram to connect this. Yes, you can run this igniton. look in the help file and use the diagram for connecting an MSD. The Crane is very similar. If you have trouble and need more assistance give us a call.

2. I am running a very large mechanical roller cam and Brodix BB2 heads and using a aerospace vacuum pump. What problems do you see with vacuum signals, can I still run the pump. I use it for scavaging and to run the power brakes. What are your cam specs? maybe you can post the cam grind or part number? With the big cam and using a vacuum pump, you will probably want to change to Alpha-N instead of Speed Density tuning. If so, give us a call and we can tell you how to accomplish this.

Been away for a couple days, My cam specs are

The SR-254 #138631 specs are: Duration @ .050" int: 254 / 374
exh: 262 / 374
Gross lift (with 1.76/1.76) int: .658
exh: .658
Lobe separation: 112

I have been told by a tuner here you could bypass the maff sensor and do a maffless tune?

[J.Wagner]

That cam should be OK, I'm just not real sure what the vacuum pump is going to do.

You should try installing the system per the installation instructions first. Monitor the MAP sensor readings and if it is unstable due to the vacuum pump you can switch over to Alph-N mode (RPM vs. Throttle).

Have a couple more issues that have come up:

1 Dizzy hits firewall (the caps too big). can you give me the part number of the smaller cap version that suits this setup.

2 I would like to use the Wide band sensor, can you give me the part number of a version that suits this setup. I bought my injection from Jeggs, would like to get it from them. They stock bosch sensors, is there one in the range that suits?

Contact Mallory and get a cap and rotor for a 6148201 and you should be good on the distributor then.


For the wideband we recomend the Wideband Commander kit made by Dynojet. They also have a Wideband Commander 2 that works realy well and it is a little more compact. The part number for the WB commander is 15-7002 and WB commander 2 is 15-7006.

[MySS427]

Went to there website, do I need the whole kit ( module ect) or just the sensor. The kit seems to be its own unit with gauges, cables and module, I was under the impression that you just plug the sensor into the Edelbrock system?

[shaun callaway]

All you need is the different cap and rotor. Your current distributor already has the sensor in it.

[MySS427]

Sorry I meant for the wide band 02 sensor, Dynojet has a kit for it but what I need to know is, do I buy the whole kit or can I purchase the sensor and plug it into the Edelbrock system as is. Or do I need all wiring and gauges ect from them, it looks like a stand alone kit.

[J.Wagner]

The wideband sensor will not plug directly into any of the Pro-Flo_2 or XT kits. It must have the controller that converts the wideband signal into a 0-5 volt output. Follow the instructions in the user guide to set it up.
