I had a "Chipit" chip installed on my 200 series cruiser and all I can say is WOW. It feels like the cruiser has lost 500kg of blubber. While the 200 already has heaps of power, it has never felt immediately responsive - my wife describes it as a tank, but she does drive a Mazda CX7 (2.4L turbo petrol rocket).
Well now the Chipit 200 a similair feel!
Gone is that initial lethargic feeling and its replaced with lively acceleration from a gentle prod. And stick the boot in and you really feel the difference. I have never chirped all 4 tyres from a standing start before (brake on - apply throttle, then release brake with full throttle) and the TRC didn't cut in because all 4 were chirping!
As we all know (
well owners do), the 200 does have a bit of "turbo lag" for want of a better word - give it full throttle from idle and it thinks for 1/2 a second before getting down to business. The Chipit has certainly reduced that lag. It is dramatically improved, but not 100% eliminated and in all likelyhood probably part of the original ECU programming so that a huge amount of torque is not dumped into CV's/gearboxes instantaneously.
Perhaps the best bit of the Chipit is that normal everyday driving (ie granny throttle) it has a markedly improved responce at much lower rpm. The 200 was accelerating noticeably faster from a lower rpm and not kicking down a gear like it normally would - that to me is going to be noticed everyday and is enough reason alone to fit one to a 200.
This fitting was also followed up with a 4wheel dyno run at
United Fuel Injection's premises. Several states of tune were tried, including pushing the settings to the point where the ECU backed off the engine power - very good to see you cannot go outside of pre-determined operating ranges and that the Chipit doesn't interfere with these protections.
With the 200 being an auto where you cannot lock it into gear, the max power on the dyno graph is only displayed above ~2000rpm, any lower rpm with full throttle and it kicks down a gear. So, the magic peak numbers were;
227kW@3300rpm and 800Nm@3200rpm.
OEM numbers were;
183kW@3200rpm and 595Nm@2600rpm.
This is a gain of some 32kW and 205Nm. Also, the graph shows a reasonably flat torque curve from 2600rpm to over 4000rpm, unlike the OEM that peaked at 2600rpm and tapered off from that point to ~400Nm @ 4000rpm (but don't forget that below 2000rpm the dyno graph is not full throttle)
As for fuel economy, guess how much throttle I was using :) However, when I did drive normally on the freeway after the dyno, it did appear to have some 10% better economy according to the scanguage - but I have no idea if this needs recalibrating after the Chipit tweaks to the readings so take with a grain of salt my economy reading - but I will post future fuel consumption over time.
The chip and wiring itself are of a very good quality. The plugs are
well made, have O-ring seals and simly plug into the original harnass - NO cutting or other modification at all. I used to have a Safari chip on my 3.0GU and it appears to be of equivalent quality. Also, I have a Scanguage and it shows no error codes from the install and according to Chipit the chip is not detectable by Toyota (unless they looked under the bonnet!). Chipit were great to deal with and they spent some 4 hours on fitting, dyno custom tuning and chewing the fat about chips in general. Would I recommend this Chip to anyone - certainly!
I would post the graph of the dyno tune if I knew how to upload a .pdf, I only seem able to upload a jpg.
Cheers
Captain
