Unichip piggy back ECU

[JCBalunsat]

They gave me a brochure of the Unichip Piggyback ECU that can improve a cars performance.

Has anyone tried this already? According to the brochure it can give a 30% overall performance either stock or modified. Dyno sheets were included on the brochure and I must say they are impressive.

How much is this and is it really worth it?

TIA

"Niky" has one fitted on his FORD Lynx 2.0L RS and swears by it's flexibilty and tuning potential even on his hard-to-tune engine.

The gains would depend on the mods you have done on your engine. The advantage of the UNICHIP is it's a programable system so if you have future upgrades, it can be re-tuned to take advantage of those upgrades.

Friend just did it to his engine. 124 hp to 136 hp at peak. Even better, midrange at around 3000 rpm improved by 15 hp.

Unichip works on modern engines that are hard to tune, that have computers that are not receptive to the more common AFCs or E-manage chips. It can work on gas, turbocharged gas or CRDi engines.

If your car is older, there are cheaper engine management systems that can still work. Ghosthunter's Apexi AFC gives similar gains on the dyno on his car (actually, better... but he's got a better engine than me, the rat... ). BUT, you still need to dyno-tune these things for maximum effect. The unichip's price already covers installation and dyno-tuning.

I've seen 20 plus hp for modern CRDi diesel engines with nothing but a Unichip and dyno-tuning. And the Unichip can be used for turbo-installs to run a fifth injector, or as a nitrous controller, or as a intercooler spray controller, or as an alcohol spray controller... the possibilities are endless.

And how much will it cost me? I've seen it on the website. 30k?

[speedyfix]

30% might be a bit high. realistically about 5% for a stock car and maybe 10-15% on a heavily modified car.

[niky]

Yup. 30k, all in.

30%, depending on where in the rpm range. I've seen 15-20 whp at certain rev ranges... if your car is making just 50hp at 3000 rpm, an extra 15hp is darn close to 30%. And this is for non-turbo cars. For turbo cars, the gains are even better.

But yeah, 30% is a big number. All I can say is, it's a guaranteed 5-20hp up and down the rev range, whatever your car. Typically, for stock cars, just 5-10whp at redline, and about 10-15hp in the midrange. You're paying the extra for this midrange, as this is what you use most when driving.
