having met john and spent a few hours(!) talking to him I have utmost respect for the man. he has amazing skills and a brain that operates on another level to most. I have a pretty high IQ but john must be off the charts. Very nice guy too and not afraid to tell what he thinks and usually has very sound arguments to back his opinions too. he has some amazing ideas about a whole range of stuff.

I've no doubt this will be off the charts. I want to go back and ask him some more stuff. just need time for my brain to digest the last bits of knowledge he dropped on me!

thanks very much bobby. I really appreciate the intro mate. and your time too. :)

You lucky duck!

Meh....the reality is that the car must have fallen short of expectations Really not sure how a full tune can drag out for 2 years... so claims that the build was f1 spec, just musn't show on the dyn

Hey Richard,

Glad that you liked the meet with John.

Yes it does get like that, does take time in digesting his knowledge.

Speak soon

Below pic, I have installed the Zeitronix Ethanol content sensor that gives you the concentration of ethanol in E85 Fuel. This is a must when running E85, last thing you wont to do is give it a hit and you lean out cause the ethanol content has changed, this is connected to a return line. Just Engine management is a Dealer for Zeitronix products.

Theres a writeup in the Forced induction section if you dont check it often, by a guy who has used that sensor with a Link ecu, a local tuner has got the car running on anything between 98 and E85. Check it out, good read.

Yes very well put together thats if you want to run 98 and E85, what i am trying to do is only run E85 however as you know the concentration varies so we need to know the ethanol contant accurately . Tune can vary to fuel temp also when using E85 i have noticed he has not allowed for that.

What's the plan to alter the mixture of E85 if it is found to be varied from the original tune state? Add denatured Ethanol and/or BP98?

What do you do with ignition tables in regards to varying ethanol content/fuel mixtures? Add an extra dimension vs ethanol content? Sounds like an absolute mission to get running at an optimum level.

I'd think that the optimum/safe ignition advance would vary widely when you started mixing fuels together, as opposed to making ethanol content based corrections to the fueling table which would correlate directly to ethanol content..

Below is an update of the wastegaste Venturi.

Progress has been slow as John is having alot of problems panel beating the 304 stainless as it needs to be annealed every time he needs to beat it and the time frame is short before it cools.

Looking great!

      RB25DE NEO with Haltech ECU

      By Haggerty · Posted

      I seem to the be only person that is using a Haltech 2500 on an NA motor, I've installed a Bosch DBW throttle body to the OEM intake manifold and am having problems maintaining AFR even with the wideband o2.  It will run extremely rich at idle and up to redline, but under load it will go extremely lean in the 20s and i'm essentially having to rev it over 4k and feather the clutch to get it up to speed.  I've read a few other threads of about the butterfly, it seems removing the vacuum to it is supposed to have it remain open, i've noticed no difference under 4k with the vacuum line to it plugged.  I'm hoping someone here has had luck using the NA manifold with Haltech, and if they happen to have a tune for it.

      I don't know any details, but I really wouldn't be surprised if they do it as a LHD only version, at least initially.

      What should I do next to hold the head on

      By Gareth87 · Posted

      Thanks for the replies everyone. Definitely a coolant push. Oil catch can is empty and always has been. As the engine is out now I'll be having a good look over things. I do have some detonation on the piston tops from a trigger issue back about 5 years ago. I felt it and shut off then bought a new ecu and changed the trigger. Never been an issue since. It never hurt the power, its made almost 80hp more since that incident but I will pull the bearing caps to take a look. If the bearings are damaged I will do a bottom end refresh. Head is being re conditioned at the moment and the block will be cleaned and checked to ensure it's flat. I'll go with a kameari gasket and see how it ends up. The other thing I'm not super keen on is the cylinder colours. I suspect this is from the inlet manifold. The plan will be to put it back together, retune and then stick a plazmaman billet inlet on it and retune. I'm happy with the power, if it makes a little more, then great, but I would rather just make everything more efficient at this stage.

      Maybe they'll look to do a bunch of presales to help inject some cash fast for their financial issues...

      Does it also misfire equally when revving?   Josh is very correct in what you should do. The coilpack harness wiring loom itself is a known problem due to its age and the number of heat cycles it has gone through. Throwing parts at a vehicle to diagnose the issue isn't a smart or good way to do it. Secondly, you may have a bad coil pack, you pop replacements in, they fix that issue, but messing with the harness breaks it, so the issue persists. So now you think "well it wasn't the coil packs" and have to continue chasing your tail, potentially swapping back in your shit coil packs and returning the good ones (yes, I've seen people do this because 'it wasn't the problem' and they want to save money). And suddenly, you've got two issues with the same symptoms...   Diagnose, don't use the spare parts shotgun.
