I didn't find anything on this product when I searched the forum. I can't help but feel that someone here knows something about them or has experimented with their technology. Best I can determine they do the bulk of their marketing and sales on e-bay. A flash chip for my STR is available for $89. Their e-bay site even included an installation video and an anticipated power and torque calculator. Normally I won't pay attention to a performance device utill it costs at least $300, but this one caugt my eye. Anyone out there used this and willing to admit it?

 

I very much doubt (*) it does anything useful, especially with an S-Type.

(*) i.e. I simply do not believe them one tiny bit

Don't waste your money.

 

I agree, guess I just always remain hopeful.

 

Yep, just another company selling snake oil to lighten as many wallets as possible while touting yet another completely false product....

 

Concur...Junk

 

So, I was so intrigued that I bought the company.

The product now costs $995.

Interested?

 

I'll let you know in a couple of weeks - I bought one for $89.00 - from EBAY for my 98 XJR - I sorta figured that I spill more than that on a weekend bender, Car is going on dyno in about 3 weeks, so you can see the facts, other mods happening at same time, - each to be recorded on a dyno run (exhaust - intake and supercharger pulley.)
cheers,

98 XJR doesn't use the same PCM so any outcome will not apply to the S-Type.

Probably still not a good plan even for the XJR...

(But by all means post the outcome anyway!)

 

You guys are fairly negative - you were being offered an opinion of a product - I havent claimed it works, and I agree - the part number I purchased will not suit other applications - But I am a mechanic of 40 years experience who has dealt with EFI since toyota introduced theirs in the mid 80's, and gave me factory training - All ELECTRONIC fuel systems use the same basics, (different voltages and resistances and different methods of gathering the required data) its all basically the same.

 

No, it's not "all basically the same".

The early systems did not have feedback loops (nor tight emissions needs). The feedback (closed loop) is hugely important and means these sorts of devices are worse than useless. A waste of money and can be damaging.

 

Good Luck with your Volo Flash Chip! I hope you have a spare ECM available and $$$ to get it reprogrammed.

 

I'd be more worried it may try to run lean at WOT...

Trying to lean when in closed loop will just make the car compensate by adding/subtracting fuel based on the O2s. May throw codes and even reduce power, too LOL

 

It seems like the OP has a "CHIP" on his shoulder....

 

dc4prez, I'd be interested to know what you find after installing the Volo, please report back.

 

Would be fun to take a set of OBD readings (IAT etc and fuel trims), fit device, repeat readings, wait a few days & repeat once more. If the car hasn't thrown any codes, still runs CL (closed loop) and the trims haven't moved to correct what the device does then expect trouble. If they have moved then it's no longer doing anything!
