Yesterday was the day to see this project wrapped up, as I took the car to Chris/Scoff at EFI Tuning to be mapped so I can finally drive it properly rather than potter around at my own imposed 4K Limit,
Just to remind you all what’s been done to this engine during this build:
- Cylinder honing
- Clio 197 Pistons
- Clio 197 Cams
- Supertech Valves
- Mild head porting
- New main and big end bearings
- Metal idler pulleys
- New dephaser pulley
- New timing belt kit
- 3 angle valve seats
- Block decked
- Head skimmed “a fair whack, Increasing the compression ratio by 1 at least“ Quoting Bloke’s comments earlier in this thread
The drive up to Runcorn was Lovley, stopping off in Melton Mowbray to get some breakfast, and driving cross country to run the car through the gears as advised by Bloke:
Arrived at EFI parts and first fitted the 197 Injectors to the engine, before Scoff spent a few minutes updating the Software on the car. Turns out that the ECU programme was the oldest 8001 version, rather than the latest 8003, so Chris updated that for me:
Next it was time for Chris to put it on the Rolllers and start to work his magic:

I was super impressed with the amount of effort and time Chris put into the work, and could see him tuning all parts of the map, not just doing the power run, but making sure the car will drive well, as well as perform as intended.
I took a little video of one of the power runs:
So enough of the text, it’s the graph you’re waiting for eh..? Well here it is:
188.1 bhp at 6400 with 167 lb/f at 5250
Little bit disappointed with that as was hoping to see the power at 190 something... but it appears that everything is not right with the engine....
Chris noticed a rattle during the mapping and saw it during the power runs also, there seems to be an issue with the BRAND NEW Dephaser Pulley as it’s rattling a little bit, and doesn’t seem to be “locking in” when the VVT tells it to?? You can see that the power really drops off after the peak. He saw during the mapping that sometimes it seems to work, and then other times not...

SH1TBAGS!!
So it appears that whilst I’m removing the gearbox to fix the 5th Gear Synchro Issue the Engine has now also got to come out to get the Dephaser Pulley changed at the same time...
Typical bloody Renault, testing my patience! I’m going out for a good drive in it today to kick it’s head in a little bit and see how it feels, will share a few pictures as it should be a good day with some interesting machinery...
Thanks for reading, I welcome your comments and feedback.
