ANY EXPERINCE OF CHIP TUNING ON 166 3 liter???

HEllo,

Would you please tell me that if a good chiptune job really makes a difference on 3 liter 166 2000??? REgards

There are nowhere near the opportunities for gain on the V6 from chiptuning as there are on the diesels. You may get 10-15 BHP.

I'd have a look at the squadra tuning site as they have had a good reputation for not 'overegging' the claims too much, and they have some before /after graphs to compare.

Actually i've just looked and they have no section for the 166..so I'd make an enquiry first just in case.

There is also Autodelta..but they have deleted their 166 mods as well..and they used to do them for sure!!!!

I'm now getting vibes that say the 166 does not have a swappable chip. You have to reprogram the existing eprom,,,so its a remap I'm beginning to think.

My vintage 156 V6 (non-ODB remapable) has been fitted with a 3.0 from a 166. Its been fitted with a BMC CDA instead of the air filter and as a GTA inlet manifold (not sure what sort of gain this gives). Straight through centre pipe after the cat and SuperSprint backbox, but I don't see the exhaust as a performance mod, more for the look and the sound.

The car is fitted with a mappable chip "Dastek Unichip" and was programmed for the car on a rolling road for 97 octane fuel, and topped out at 245bhp on the day. So 25bhp over the standard figure. However, I have on good account from Augusto at Red Dot, who has mapped quite a lot of GTV's fitted with the 3.0 V6, that usually these engines produce about 10bhp less than the claimed 220bhp.

Yes, I have a dastek unichip Q+ with a raggazon exhaust and now working to fit GTA inlet cams. Without the cams and the exhaust the dyno reading went up from 268Nm to 289Nm at engine and from 176kw at engine to 183.6kw.., I have the dyno sheets so will post them for you to see, only problem is that the gearbox changes to 4th at 6400 and the kw were still rising to if you can get the gearbox to change at say 6800 there will be a significant difference in the power. I don't trust the dyno kw reading, think it's at least 10Kw more, so i'm looking at getting a second opinion, but the pre and post readings were taken on the same dyno, so the difference was about 8Kw and 21Nm over stock.

After fitting the cams a second remap is on the cards, then i will get dyno readings from 2 different dynos and post.

(After remapping though, please note the gearbox goes funny, it changes gears earlier. I think the gearbox can measure the torque or something because it keeps changing slightly earlier than it used to, maybe cos the torque has increased, and upon reaching a said reading, it's computer tells it to change gears... my feeling only, as this is what my 166 is doing. in sport though, its the same.)

Finally, yes you can feel the difference on the road. The pulling is better and harder, and the fuel consumption actually reduced for some odd reason. Maybe the cars are set rich at the factory and the tuner managed to get it to run leaner and more efficiently.. Q+ is the way to go and if you are in the UK they have a dealer. Just do a search on the net..

Cheers

Hi!!!

Maybe a "knocking" is the source of this behaviour...
Did You tried to modify the ignition position?
When knock sensor said "knock" to ECU, the ECU will shift one gear upper ASAP if the rpm is high... as I experienced...

I'm just thinking about power up my 166 - 3.0:

My plan: GTA inlet + camshaft +injectors (I'm looking for 2nd hand from these stuffs...any idea where can I buy?), exhaust, air filter, remap.

Is it enough, or is there any simply modification what is increase the performance?

(I'm thinking about changing the quartz inside the ECU and Gearbox ECU... maybe the communication stay good, and the rev limit will higher thanks to a few percent different clock... As I know there is no any way to change gearbox rev limit higher...)

I can recommend Squadra highly, they remapped my GTV V6 3.0 and it runs a lot better then before. Not a huge increase in power but a much improved throttle response!

They do list the 166 in the pricelist but you have to send them your ECU to be remapped (or visit Holland ).
