    I want to give a big thumbs up to the team at CPG, in particular Chris, who has been helping me with my FAST EFI 1.0, and this forum who've been lending insight as well.

    http://www.cpgnation.com/forum/threads/ez-efi-gremlin-need-help.26560/

    We've spent the last few weeks chasing a gremlin that really stumped us. While I understand its rare for the ECU to have an issue, it appears that CPG service dept infact did find one in mine after I sent it in. Keep in mind that my EZ EFI has worked flawlessly for the last 3 years, and then suddenly after what we believe was a voltage spike, the system became inoperable. WHAT DID CPG DO? Chris and team reflashed the ECU, updated the firmware, and ran the system on a test engine for an hour.... and now are returning it to me for install... NO CHARGE. ***THAT's CUSTOMER SERVICE! You've won my future business for sure. Thank you for spending the time you did on the phone with me to sleuth out the problem, and then to take the time to get it right. I'm truly impressed and grateful. Can't wait to get my Vette back on the road.

    So the bottom line was... a firmware upgrade was all the ECU needed?

    Glad they had you sorted. I am still awaiting on how they will rectify my ECU - has a random false lean reading that I have isolated to the ECU via a very painful and expensive process of elimination. I am thinking it may also need to be returned :(

    Fingers crossed! It arrives tomorrow am, and I'll be putting right in. I've double checked all wiring runs, installed the new MSD Heat Module with Tach signal, etc., etc.,... So I'm hoping all possible issues are in the clear. I'll keep everyone posted.

    SUCCESS! The ECU arrived, and I installed, set up a new tune and she started right up. After warm up and setting targets, I took it for a spin and it's purring like a tiger. Very happy to have this solved and thanks to all for your input and Chris at CPG for the repair. So thrilled to be back on the road again.

    Tha
    Chris at CPG told me the analysis of the ECU showed it was definitely corrupted software, showing signs of incomplete update etc... They reflashed it, and updated the firmware to current. So in short...YES! : )

    While I start to put miles on the ECU to build up the self tune, I do have an HEI / Timing question for the experts here: I'm currently running at High Altitude (Denver) 5200ft, a Crate GM350 with Mechanical Tach HEI & Heat Module and the FAST 1.0 EZ EFI / ECU. My current setting on the flywheel is 0 degrees TDC and all is running smoothly. However, the car has never had a huge amount Torque / HP. I'm now running an electric fan to remove fan clutch drag. ??? Should I be thinking about distributor phasing or locking out the distributor or ???? I'm getting clean firing with nothing seeming out of normal. The HEI Distributor still has active vacuum advance and the rotors centrifugal weights are fully functional. Would I get better results by locking out or does the EZ EFI 1.0 with the HEAT Digital Module already delete this and provide their own inputs? I'm simply trying to achieve the best tune to give the engine the peak tune it's capable of. Looking forward to any thoughts to help me learn more about it.

    Thank you. That's helpful to hear. I will NOT lock out my distributor advance. I was studying how to do the Total Timing average. Per your note, I'll try 15 degrees BTDC.

    Very helpful. I may indeed experiment but ultimately take it to a speed shop. It would be great to truly have it set to peak performance. My gratitude.

    Thanks... Yes, I'm working on this myself this weekend to start. I have the engine learning. I'm going to target at idle 12 degrees BTDC, figuring the mechanical vacuum adds another 10 degrees at 2000 rpm, and then do "black" (light) centrifugal springs to try and add another 12 degrees.. Total timing at 34 BTDC advance. Thoughts?

    Thanks AA. Quick question for you. I am doing a little tweaking myself to learn before having a pro tackle it. While in the process of the first few miles, I'm having a little trouble with the car running fine during load, but when I take load off and push in the clutch to stop at a light, the rpm drops so low it sometimes stalls. Sometimes it recovers, but it obviously needs something. Should I let it learn this? Or is there a setting I should mod in the base tune? I'm currently at 750rpm idle, and have scanned the TPS since adjusting the idle screw per instructions from EZ EFI. I do have a +1 setting on the advanced menu for ACCEL. Thoughts on what I can do to help stop this stalling? I haven't reset timing yet to my plan of 12 degrees BTDC. I think I'm at 0 right now.

    Thanks AA. Here are the details. I think I have it a little steady when I recal. the TPS at 800 RPM Idle and opened the blades slightly till I was in the cal range bouncing toward the left side. Page 1 = 800 RPM - (-02 to 00) 2 C% Page 2 = 800 RPM 15-20 IAC *Very active as it tries to keep idle steady. CTS 211 TPS 00 Page 3 = 13.8 - 13.3 44 MAP 129 ATS Page 4 = 01 Load 44% 02 800 Let me know your thoughts. I am at 0 degree TDC right now and the temps are running hotter than norm which usually is around 190. I think the electric fan isn't quite as good a the cooling as the manual, but I wanted to get rid of the drag on the engine. *Yes it sometimes wants to die whenever I took load off the engine and it was to return to idle... it would go past idle and sometime couldn't recover. I'm hoping my blade adjustment and timing will help this. Waiting for it to cool a bit to set timing.

    One more comment on above... I've now set the idle to 14 Degrees BTDC, and my vacuum on a manual gauge is about 10 to 14.... is that too low? I've checked for leaks but not finding any...

    I have found a spark jumping on one wire. I'm going to replace or shield it.

    I will replace tomorrow. I've shielded it for now and set timing to 20 Dgrees BTDC. After re cal TPS things seem to be settling down a little. Stay tuned and thank you for your very helpful guidance. Its really appreciated as I'm learning.

    Changed the timing to 20 degrees BTDC as you suggested. I've moved the RPM back to 750 and re adj. the TPS and set screw to target. I'll work on the AF today..

    OK. I have the AF mixture at 14 for Idle and 14.7 cruise. I noted the WOT is at 12.8 and haven't touched that. Timing is at 20 BTDC and the engine seems to be idling very happy. I'm taking it out today to get it up to temp and see how it goes. Without a doubt it's happier when I give it a little punch and it returns to idle. No more dip and struggle. : )

    Thank you. Just took it for a light drive for about 5 miles. It does start to ping at 2300 RPM under load. I stayed below that and brought it home. It seems to be finding it's idle now after some bouncing to 500's then back to 800...eventually finding 750. No stalls. I will keep the WOT at 12.8 for now as I haven't even tried that yet. Should I back down the advance to ____ ? Anything else on the computer to help compensate the change?

    So I should back down the timing off 20 degrees ? I do have the light springs on the mechanical advance right now. Should I test and go 1 light and 1 media (silver) or move completely to (silver springs)? Any suggestions on a good speed shop who knows EZ EFI in Denver area?

    It is an MSD "Like" distributor. There is no bushing stop on the bottom of the cam that I could find. I just changed out the weights, center, and used the silver heavier springs from a new HEI Slope Advanced Tune Kit I purchased at AdvancedAuto. The car is knocking a little after accell and letting off the gas, it happens when I put a little gas into it for lightly cruising. I had a squeal under the hood and the it stopped. I suddenly noticed I lost my TACH gauge. Obviously, the new angle of the distributor housing didn't suit the cable connected gear for the mechanical tach. - - Typical : ) There's always something to repair on these cars! Otherwise, I'm thinking, I might be getting a little closer. I'm going to back down timing every so slightly to be safe until I find a capable speed shop in the area that knows EZ EFI's Let me know if you have any more thoughts.
