Jeez.....not updated this for a good while, I still have the Boc, She's still healthy and pulling like a freight train!!
so what's happened in 18 months....
Build part 2...
Last update I was waiting on getting back into my original tuners to tweak the tune after all my head and refresh work however after all the messing about previously I just didn't think he was the right person for the final tune, so I set about looking elsewhere.
In the meantime a few more mods were added......
Firstly I swapped out the modded actuator from Venom to a Forge Unit with a blue (13psi) spring.
Installed a VIS HPFP piston upgrade to
help with final tuning.
I had the wheels redone in a gold colour from Kia
Lastly I took the front bumper & splitter for a repaint plus did a kind of Gloss Black on Satin Black BOCANEGRA lettering on the front (which sort of works)
12 months of attending shows, track days and just general driving later the gearbox developed a squeal on cold starts ,I later found this to be a dry clutch release bearing, so tuning on hold and a new LUK clutch pack & flywheel installed by Lancashire Transmissions (quick turn around, highly recommended)
Having left the clutch to bed and settle in for a month I made the best decision of my build to date.
Being a member of this forum and seeing the great tuning work done over the last 15/20 years on BAM engines and alike plus having been involved in the tuning development work for many Venom hybrid's it dawned on me to ask Rick @ Unicorn if he would be willing to finalise my tune
although being aware the EA111 1.4 Twincharger isn't a platform Rick would generally take on due to it's reputation (understandably so).
So where did I differ?? As above really, being the ONLY UK Bocanegra (Possibly ONLY UK Twincharger) to be running a Venom K03 Hybrid (who unfortunately are no longer trading) and I think Rick showing some sympathy for me and my 2 year plight to complete my setup
Plus the fact I have taken VERY good care of my engine/gearbox which was evident when data logged by Rick he agreed to retune the BOC
After an initial base run, to completely rewriting the tune and then fine tuning.... 5 hour's later she was off the rollers with a 1 off tune and honestly can't thank the Rick, Mario & Chloe @ Unicorn Motor Developments enough, Absolute night and day difference from the previous tune,
Rick has maxed out the stock injectors and running close the maximum fuel pressure with the VIS HPFP for a HUGE torque mountain in the mid range just as the Venom K03 is on full chat making 1.7bar @3.4K, Holding 1.6bar with a steady taper down in the redline with perfect boost control from the stock N75 and Forge actuator.
I know there are higher figures (few proven, many not) all over the internet AND I have made higher figures on a previous tune however peak numbers are not the be all and end all, Delta under the curves IS, To be hitting peak torque of 273ft lb @3.7K and peak hp of 237 @5.4K all within everyday engine rev ranges is Useable Power!!
Strangling the engine to death to hit some 7k+ hp peak figure pushing a turbo out of it's efficiency zone and making hot air just isn't practical....it's NOT a VTEC!!
So YES...A Quicker, Happy, Healthy 'stock internal' Boc running a hybrid no less!!
Post tuning I had a few upgrades and maintenance bits still on the list to sort.....
