today I was going to load the shark injector in my car. I have about 4000 miles on the car, so the battery is all but brand new. I purchased a good charger yesterday that has a 10 or 30 amp charge rate. I have followed the directions perfectly, and I have a multi meter on the battery that is reading minimum of 14.5 volts on the 10 amp. More like 15.5-16.3 with the 30 amp charge rate, and the shark reads out a code that is saying the battery voltage is too low. I just don't get it and I am now regretting my purchase, after all the piece is not returnable. If anyone else has had this or any other problems with the shark please let me know. :???:

 

Give them a holler. Maybe you got a bad one or something.

 

I personally know of two MCSs that loaded the Shark w/o issue having a battery charge attached.

I have installed and removed my Shark several times and only had the Voltage issue one time. It was well below freezing and the car had not been run much for a few days. I waited til the weekend took it for a spin and then completed the job in the garage without any problem.

I ask the obvious.

Daylight lights? - handbrake on to kill
steering pump? - pull fuse
Other electronics? fan climate control etc?
Charger not properly hooked up. I noticed if I put it onto the motor mount it didn't wwork properly - need to be on body

I don't know where you bought but Eurosport where I got mine has a return policy and they are helpful if you contact them.

I had a little trouble with my Shark and v32 software but all is well now I am at v36. I like it. had one on a Z3 and was happy then too

 

>>the shark reads out a code that is saying the battery voltage is too low. I just don't get it and I am now regretting my purchase, after all the piece is not returnable.

I had his problem with the Shark and a brand new Sears 40-amp charger. It seems that the charger generated quite a bit of electrical noise at the higher charge rate settings, and the Shark interprets this a "low voltage". I was able to get the Shark working only at the 2-amp "trickle" setting, and finally just quit using a charger altogether... just be sure the battery is in good shape, and maybe pull the PS fan fuse just for good measure.

I regretted my Shark purchase for other reasons, and finally sent it back within the 30-day return window. Actual dyno testing (see picture) confirmed what my "butt dyno" had led me to suspect... performance with the Shark was actually LOWER than with the stock v.36 ECU maps! The Shark was also producing ultra-rich AFRs, which were pretty scary, too. I'm running a Superchips ECU mod now... with dyno-confirmed improvements over stock!

^^Yikes!! I'll take that possible mod off of my list!
