Fast efi 2.0

[obengston]

Okay just finished the install. So far everything feels good, and seems to be responding well. I have not taken it very far on a test drive, basically through the neighborhood, just want to feel comfortable that its not going to cost me a tow truck ride back home. I did a quick video of the basic things I have done to the car as well as the 2.0. Don't laugh at my lack of mechanical ability, but almost everything done/installed on the car I have done myself in the garage.

I will clean everything up once I know it is good, and make it more appealing.

Is your electric fuel pump up in the engine compartment?

[obengston]

No its in the tank, I installed a aeromotive stealth tank.

I Think I may have spoke to soon. I have been working on this thing ALL DAY. Not sure whats going on. Yesterday, it seemed to be working fairly good except it would still loss power/communication and shut the car off, but would start right back up. I took it on about a mile drive, and it shut off going down the road but picked right back up. On the way back the o2 threw a code, but reset. I got it home cleared the code and it started right back up, so I parked it in the garage. This morning I figured I would take it on a longer drive so it could self learn. Well never made the ride. It started right up, but I could not even touch the throttle because it would flood. I reset the timing, and reset the ECU. Still no change, and would still lose communication and turn the car off. I played with the wiring all day, called Fast tech several times. I do have the power, and ground wire run to the trunk to the battery, the two wires runs right along side the 1 gauge wire running from the battery to the front where its connected to a bolt that passes through the floor, and connects to the alternator and starter. The Fast tech says the two wires may be picking up to much noise from the 1 gauge wire. So I will run two wires outside the car to the front and connect it to the ECU and see if that changes anything. Thats going to be a couple of days, because after starting on the car all day my starter/flywheel started just spinning, so got under the car so the starter bolts had became lose. Tried to tighten them and one broke off, so hopefully it did not brake off inside the block, but I think it did. So now its like going to the doctors office for something, its a guessing game until I find the solution.

Well fixed the starter. Called Fast again, still another Tech going through the same scenario explaining from the beginning of whats going on. Having them ask basically the same questions. So I decided to eliminate any future questions/concerns from them about maybe electrical noise. I basically pulled the system out (all wiring). I ran all the wiring outside the car to the trunk for power, ran the wire to the MSD (thats mounted in my driver kick panel) across the windshield into the driver door. Placed the ecu and harness on the passenger fender. The harness that runs from the throttle body to the ECU is going straight over to the fender and connected to the ECU. So the only wiring thats going into the car is the handheld unit. The cable to the 02 goes straight from the ECU (on the fender) down under the car to the exhaust. I filmed this as well and started the car up. Started up no problem, once it gets warmed it seems to being good at running, but as soon as you attempt to give it any throttle it starts running extremely rich, and can't seem to correct itself at all. So I filmed all this today as well as showing the live data screen the entire time. About 20min worth. I'm currently posting it on youtube, and going to link both of the videos to Fast Tech site, so hopefully they can see and maybe come up with a better solution. I will link that video here as well if anyone wants to see it, and see how bad I have pulled the cat apart compared to the first video.

I think with 4500 views on this thread, you've got a lot of folks watching to see how you come out on this.
Thank you for posting your adventure!

Here is about 20 min video of this crap...

At this point I have invested well over 3K into this system. I was really excited to see it come out. I upgraded my entire fuel system to support this system. I purchased a new MSD distributor, ordered a new Nitrous system to support the higher fuel pressure, Sold my $800 dollar Pro Systems carb (for $400). Took out my manual timing retard system, rewired everything to support this system, cut some sizable holes in the firewall all for this system. Now look what I have going on. Really regretting selling my carb (unless this thing can magically fix itself).

Hey I watched your video and I was wondering if when you adjust your IAC into the target range (green) that makes your a/f ratio to fat. Maybe the throttle blades need to be a little more open for more air, the instructions say the target area is not for every application. Just a thought as I am just starting my install and am nervous about having the same issues....

[obengston]

No not the issue here at all. Had nothing to do with what was going on. If you look at my first video (the first day I started it it ran great and I drove it around) on that day the MAP/Load is around 70 at idle , on the next day the second video shows the MAP/LOAD at 100 plus at idle, pretty sure that might have something to do with my issue. That is the only difference between the two days.

Hopefully will get a new map sensor this week from Fast if they send me one out. (for free...)

After watching the video, I have a question.
Did you calibrate the throttle position sensor?
In the video ,the throttle position gauge indication does not seem to smoothly follow depressing the throttle.

Yes, several times. Pretty sure or hoping the issue is the MAP sensor. If I get it in the mail tomorrow I will post the results good or bad.

[obengston]

Well replaced the MAP sensor today,...and wow the load/map reading went back down an the car ran great. Drove it about 4 miles. All seemed good. I will drive it many miles tomorrow and report back on how well it is learning

[garry1172]

Even though I have a Mas-flo set up this is a really interesting thread

beautiful Camaro

Happy to hear initial success replacing the MAP sensor.

[obengston]

Took it on about a 20 mile drive, running it up to speeds of 70... Everything seems to be working great, response is great...keep the fingers crossed. Cranks up without having to touch the throttle at all, controls my timing, the cooling fans...

[Spork82]

That's great to hear, I just got my ez-efi in the mail today and can't wait to play with it!

[mmosley]

Wow! Did you return the old map! Ask them to do failure analysis... determine cause or mode of failure, possibly screen future MAP sensors so your brethren do not have to experience the same issue. You could have just as easily given up, got your money back, moved on and put a stain on their reputation. As it is, put you down for a while. Did they have anything to say?

No didn't return it, but when I pulled the one out the isolator (rubber piece that surrounds the end not sure of the name) was torn.

I did go dive it again about 10 miles playing with it some..letting it learn more. It did really good. I now have everything nice and installed. I will have to take another video of it to show how well it looks and runs (but its all hidden), looks good.

Thanks for posting all the hard work you've done. I'm waiting for more info from other buyers before I purchase and your posts have given me more confidence with the FAST.

Keep your PT brethren in the loop!
