You mean since I had it running the other day then the grounds must be fine? I will get it shipped out Monday first thing.
Thanks
Keith

 

Not necessarily must be, just very likely.

Ken

 

Shipped out to Ken today. Will be there in a few days max...
Thanks
Keith

 

Any word on that MS Ken?
Thanks
Keith

 

I think they tried to deliver it on Friday, but I have not had a chance to get to the post office yet.

I'll go there today or tomorrow and pick it up.

Thanks,

Ken

 

Alright, I picked it up this morning (sorry it took so long, work has been nuts).

I'll get a look at it this weekend and fix whatever is wrong, and send it back early next week.

Ken

 

No big deal, Thanks so much for checking it out, let me know how it goes.

Keith

 

So I checked all the wiring and it all looked fine, but the hysteresis potentiometer was turned pretty far clockwise. I turned that counterclockwise all the way, and will test in my car tomorrow evening after work.

Ken

 

Awesome, Let me know how it turns out. Would that make it do wierd things?
Thanks
Keith

 

It could if your CAS's sensor gap was just on the high side of the spec.

Ken

 

How did it run on your car?

Keith

 

I've not actually had a chance to try it yet. I've had to work late every day this week so by the time I get home, it's too late to start a loud car in my townhouse neighborhood.

I'll keep you up to date, sorry it's taking so long.

Ken

 

Its all good. No rush, let me know how it does.
Thanks
Keith

 

Ok, it starts my car just fine every try. It is on its way back Monday.

Ken

 

Sounds good man. Ill pm ya.

 

Oh and how was the adapter and wires? Did you change it any?

 

The adapter and wires seemed fine. I tried wiggling them and stuff and couldn't cause any problems.

I did 2 things since I had it here. The first was turning the hysteresis pot on the Ne sensor input to fully counter clockwise (which is what fixed the problem).

I also put a jumper to ground on pin 14 of the lm1815 circuit. This reduces noise on the 2nd trigger, and while you didn't NEED this, it should make starting more reliable if you had noise issues.

Ken

 

Sounds Great man. Cant wait to get it back and get tuning.

Keith

 

Got the MS today, works great, I will be tuning tomorrow.
Thankyou Ken. You are the man. Pm me for shipping costs.

Keith

 

Glad it's working for you. Let us know how tuning goes.

Ken

 

Tuning is good so far, messed with the low boost/no boost fuel all day when driving, then tonight I started with the WOT got it holding 10.8-11.3 afr all the way to redline at 13-14 psi. Pulls really strong, although it seems the boost has hit a brick wall at 14 psi, I had the boost controller turned as far as it would go to up the boost and 14 was as high as it would get.
I do have a small exhaust leak between the engine and manifold, that must be holding the boost back...

 

How does this look as far as settings and what not? Too much fuel for 720 primaries?

Now that its becoming colder I have noticed it takes longer to start the car. Its pretty good once its running so I think the after start enrichment is good.

I would assume I need to adjust the cranking settings injector ms for lower temps. Which way should I go with the values to make it richer? Higher or lower ms?

 

Higher pulse width is richer.

Ken

 

Thanks Ken.
