There is a website that I found that is offering Japanese 'piggy back chips for any fuel injected car. They normally retail at 69.99 but are offered for a crazy £4.95 including post!! Apparantly they take five minutes to fit between the AFM and ECU and increase powere by around 5-20 BHP. Spoke to Adrian at Alfaaid and he reckons they shouldn't be a problem to fit to a Injection 33 (8 or 16 valve). The site is

xtreme-car-audio.co.uk

If anyone checks this out then let me know what you think?

Cheers Paul.

p.s I've ordered one for my 16 valve, so if it's crap then I've only lost 4.95!!

The part arrived in the post today and unfortunately it is a bit crap, just a tiny resistor or something with a thin wire coming out of each end. Apparently you disconnect the air temperature sensor lead and bridge the connector with this thing and it fools the ecu into providing a richer mixture or more fuel under acceleration. It looks shit though and I'm a bit worried about trying it. Any suggestions..maybe bin it??

Cheers Paul.

Hi

The temperature sensor just works off resistance, so the extra resistor just goes in to make the ecu think the engine is colder than it really is and so richen the mixture.

A very crude way of adjusting the mixture.

All the best

If you look on ebay, they are a little more expensive, but do come in a plastic box!!!

Basically it is a bodge and fools your ecu/engine into thinking the engine is colder than it actually is and makes it run richer/changes timing (clever automatic choke type program in the ECU). It will probably foul your plugs, and make you burn more fuel per mile.

Not the greatest mod, and I would not fit it on my car.

I would be suspicious of any engine mod that offers 5+ bhp, and is less than £100. There is no such thing as cheap extra power on standard power output, or the manufacturer would have done it as standard.

Hi Matt, Thanks for the advice about the crappy mod resistor!! It has already found it's way into the bin. Think I'll get myself a BBR Starchip as they are only £121 inc vat and post. Cheers Paul.
