Oigen 9 2 Cars Posted December 3, 2006 Hi, I want to rebuilt a DFW engine and convert it to D6C. If I change the pistons, inlet cam pulley and ECU with D6C ones, it will work? Or there are others things that I must change? Regards, Dan Share this post Link to post Share on other sites

Or there are others things that I must change? Regards, Dan Just change the pistons, that's all. The DFW ECU and pulley works really well with the extra CR.

Oigen 9 2 Cars Posted December 4, 2006 But the knock sensor? Higher CR means more chances to start pinking, no? Regards, Dan Share this post Link to post Share on other sites
petert 586 Posted December 4, 2006 No, I run the DFW ECU at 10.8:1 without any problems. It makes fantastic torque and power. Share this post Link to post Share on other sites
welshpug 1,657 Posted December 4, 2006 (edited) the knock sensor just means you have a higher level of control over the ignition. remind me what the DFW is? late spec cat equipped 1.9 16v? Edited December 4, 2006 by welshpug Share this post Link to post Share on other sites

migti 0 Posted December 4, 2006 hi am i right in saying the engine/ecu will run fine with knock sensor disconnected? Cheers Share this post Link to post Share on other sites
petert 586 Posted December 5, 2006 You have the DFW engine with D6C pistons in it? no, decked block and liners. I've built a few engines like this. am i right in saying the engine/ecu will run fine with knocksensor disconnected? if the knock sensor is disconnected the ECU retards the ignition advance severly.

migti 0 Posted December 5, 2006 cool asking because im using a early engine with no knock sensor on a loom that has the knock sensor plug, can the knock sensor be fitted onto the early block ok??> Thanks Share this post Link to post Share on other sites
welshpug 1,657 Posted December 5, 2006 yes, but theres no point unless you have a later Knock sensing ecu, the loom may well have a plug for the knock sensor if its close enough to the transition period to the later engines/ecu's Share this post Link to post Share on other sites
migti 0 Posted December 6, 2006 can anyone tell me if i have knock sensing ecu? is there a power diff between them? cheers again Share this post Link to post Share on other sites
KRISKARRERA 2 1 Cars Posted December 6, 2006 can anyone tell me if i have knock sensing ecu? is there a power diff between them? cheers again What number is the ECU? Do you know the age of the car it came from? And where the car came from? There is no power difference so long as you use 89 ron. Share this post Link to post Share on other sites
petert 586 Posted December 6, 2006 3 row ecus (55 pin) have knock sensors 2 row ecus don't Share this post Link to post Share on other sites
sorrentoaddict 1 Posted December 27, 2006 just take the entire knock-sensor off the block (do not disconnect it), and bolt it to a simple fabricated metal/rubber "holder" that can be fitted to the bulkhead or similar place around the engine. Then the engine ECU will be cheated into thinking that there is no pinking going on in the engine. A cheap trick - works to some extent. If overdone, you might damage the engine, of course.
