Fuel Injection Fix

Mark,

Thanks for the vote of confidence on Second Street Speed!

I feel better about my choice already!

I will post the results(provided the RWHP numbers aren't

too embarassing!) /ubbthreads/images/graemlins/wink.gif

I'm so pissed at my old ECU manufacturer that I just had to

change the name in my signature. /ubbthreads/images/graemlins/mad.gif

The old one began and ended with an "S", and I believe that

there was a "D" in the middle! /ubbthreads/images/graemlins/wink.gif

Upon further research into my manifold, Bill at Second
Street Speed has decided that a Motec M4 is the way to go,
for my application. The Accel rep admitted to Bill, that
the Gen 7 might not be the best choice for individual TBI, hence the change.
I should have it installed by Monday afternoon.
ECU and harness-$2,100, Dyno tuning(3hrs)-$450
If it gets my car back on the road, it will be
money well spent!
Now, if he can only sqeeze me in on his dyno schedule
before the end of next week! /ubbthreads/images/graemlins/grin.gif

Guys,

As some of you know, over the past few months I have been through hell, trying to get my engine started with an SDS EFI system. I am getting no injector activity or spark signal to my MSD box.
Below is a list of what has been tested, replaced, etc.,
as well as SDS suggestions on what to try.

1. All wiring checked tested thoroughly by me, as well as multiple professional mechanics. Wired correctly. Tests OK.
Continuity everywhere. Switched hots are correct. Grounds are grounded.

2. I assumed that either the coil or MSD box was bad at first. Replaced both.

3. The ECU shows that the Hall sensor is reading trigger magnets OK, while cranking the engine over. According to SDS, this means that a trigger signal is being sent. I have tested the trigger signal wire with a wave form generator, nothing(before and after returning ECU)!

4. Voltage is OK (tried a jumper battery, then wired ECU to another battery to eliminate any possible chance of a voltage drop)Zilch!

5. Present MSD box and coil test OK. Old ones were OK too!

6. MSD box and coil are hot(+)

7. Injectors are hot(+)

8. Hall sensor has been adjusted a million times (from 0.07mm to 2.5mm), nada!

9. Pulley magnets have a difference in height of only
3 thousandths. Per SDS, that's fine!

10. I sent the ECU back to SDS, and they bench tested it, and supposedly had it hooked up in a car. Tested OK. Right!

11. SDS insists on FedEx shipping, $89 + $30 return shipping
Ouch!

12. Re-installed, tested everything again, still no signal!
Go figure!

13. SDS blames problem on injector harness ground(spark trigger signal is connected to it)in the ECU.

14. Grounds test OK, AGAIN!

15. ECU goes back to Canada again! Another $89! This is getting old!

16. They say it tests OK again! I have my doubts!

17. SDS's latest suggestion is that my MSD box is bad.
The MSD box has absolutely nothing to do with the injectors, and is after the trigger signals split, in the chain of things. Is somebody pulling MY chain?

18. I am more pissed off than ever!

19. My sanity: Questionable!.... Stress level: Through the roof!

20. Just received a new Motec M4 and harness today!!
Happy again! YAY!

21. I have figured that SDS stands for Simple Denial Strategy, as that's what they've done with me!

22. Asked for a replacement ECU. Response: We tested this one, and it's OK.

23. SDS still has the ECU. Should I tell them where to put it?

24. I was under the impression that the customer is ALWAYS right. Did somebody change this rule of thumb, and not tell me?

Have I missed anything? Suggestions welcomed!

I posted here for suggestions. I apologize to the moderator.

Please move it to the Consumer Alert forum (Fraud Division),

if you like. I would have posted it there too, but my

typing finger is cramping up!

Bill,
I feel your pain!
I had issues with my Haltech when I started the enigne. The fuel part was OK, but the direct fired ignition was a bear. It was misfiring, popping back into the throttle bodies. Nasty. I spent a week looking at wiring, watching things with an O scope, moving the Hall switch in and out, etc.
I was ready to abandon the direct firing and put a distributor in. Sent the ECU to Texas for a check out. No problem.
It ended up that I had purchased the Hall switch a year before the ECU. In that time, they had changed the ECU electronics and the Hall switch with it. Simply put, the Hall switch I had was incompatible with the ECU. A new switch was like night and day.

It doesn't take much to make the system sour. One little thing....
In the end, I'm glad I stuck with it.
Hang in there!!
 
Surprise, surprise!

My e-mail contained a letter from SDS today.

It was not any sort of admission of a problem with my ECU

on their part, but did admit that the harness MIGHT have

a problem. The part about fully refunding my money, if I

shipped the balance of the system back to them, practically

knocked me over! /ubbthreads/images/graemlins/shocked.gif My faith in a god, has been restored!

Hallelujah brothers!!!! I have been SAVED!!!! /ubbthreads/images/graemlins/grin.gif

Nice to see that that SDS is willing to stand behind their

product, albeit a bit late in the game. AMEN!!!!
