Cant believe you made it to me actually. 2 injectors earthing through the wideband!! Essentially resulting in 100% duty cycle on 2 cylinders at all times... eek.

 

202@wheels, wow! Mind tell boost level?

How much do you think is possible with a td04 on stock internals 99 1.8?

 

yeah I know nick! I was fortunate to make it! ive since wired up the wideband to a different power feed on the eco (the one you showed me) and its all looking healthy. idles and cruises at 14.7 and 12.5/13 under full boost. well chuffed with how quick it is!

The car made that power at 11psi but it also made 178whp at just 6psi

 

A couple of questions, did you take your own laptop with tuner studio on or just let Skuzzle use his?

Also on boost shouldn't you be 11.5 AFR no 12.5?

 

I'd rather run a bit richer and make a little bit less power than have 13 AFR at full boost on a turbo converted engine.

 

My wideband was giving 11.8 in full boost.

 

And i trust my wideband much more than most diy ones.

Anyone would be a fool not to trust you!

You sir are a god amongst men, all hail the mighty Skuzzle

 

Erm... ok

If his is some monkey home brew one, I agree totally.

But I do struggle to trust people, as seen it too many times.

Even just last year, I got a car back from one of the best known mappers in the UK, and he clearly didn't know I've got all my own equipment to test AFR. And after not being that impressed with the drivability to say the least (bloody fast at full throttle mind, but that's easy) on the way home, I checked it out.

On three different (expensive, pro) widebands, the AFRs, while fine at cruise and idle, were very very low 10s and high 9s on boost. That's beyond 'safe', amazing it wasn't misfiring, but it did need very small plug gaps and was running coil on plug.

He gave me my money back.

 

Stav, if you have all your own gear and know what you want to achieve with your tune why are you not doing it yourself?

You can do most of the bigger throttle stuff on the road. On a turbo car the ign advance will be det limited so easy to set up at these points.

Then hire a dyno for a couple of hours to run through the small throttle openings.

Because I know it's just not as simple as that tbh mate.

Hence why I think 99% of self proclaimed mappers in the UK are pretty shit at even doing the basics of power and reliability, never mind drivability, despite all knowing 'how' to do it.

IMO mapping is the most underestimated part of all tuning.

 

It can be for sure but the hardest part is making a solid map consistent. Heat soaked sensors etc can all very quickly make a car run rough as hell which was set beautifully on a dyno.. the biggest problem i find regularly is after cool down to say 50 deg coolant after a mapping session and restarting a car.. often heat soak on the iat will cause chaos for a few minutes.

 

And theres no tuning it out really as if you tweak the iat youre messing up an area that may be right if intake temps are actually that high in boost for example.
So then its finding a balance of warmup etc to try and solve an issue brought about by poor placement of sensors etc.

 

Just wanted to add to this thread as my first post here..
I recently turned a £300 1.8 MOT-less wreck into a bit of a beast using a TD05 16G turbo off a subaru. I'll upload some pictures and post it in the newbies section later on tonight..
I spent quite a long time choosing a place to map the car, as its mostly hand built by me and I know how easy it is to blow one up. I ended up booking it in with Nick @ Skuzzle motorsport, and I am over the moon with that choice.
I turned up running on mostly two cylinders and left with 221hp at the wheels the same day.. All for a great price, the guy is an absolute gent and I couldn't recommend him more.

 

221@ wheels! sweet! what subaru runs a td05?
