I understand there is no definitive answer to this question, and it all depends on engine condition, fuel, maintenance etc.

 

My car has the mushroom air filters, a mines ecu, a FMIC and a decat exhaust, everything else is stock including injectors and turbos. The car has a boost controller on already and is currently boosting at 10psi. Is there any room to increase this? Obviously I know the higher the boost the higher the risk to everything but was wondering if anyone here with a similar setup could say they have safely ran X amount of boost for the last X amount of time without issue..

 

Thanks, Dan

Just get it on a dyno and have them turn the boost up whilst monitoring AFR & knock. That's the only answer, really. Anything else is just a mindless guess as to what your specific car can do. The first guy may have base timing at 13° without even knowing it, then the next guy follows him blindly and kills his engine.

Yes, ideally I need to get the car booked in with you on the rolling road asap and get it mapped. Can't see me getting the time before October now though. Cheers

If all you're doing is turning the boost up, you can use anyone as long as they know what they're doing. Or the other option is to just turn it up and see what happens. It's a terrible idea, but it's the same as going on someone else's estimate from a forum.

Jeff sets them up to boost at 1 bar if that helps ?

On a Mine's ECU with base timing at 15°? That's brave :wack:

Nothing brave Noel, firstly we do not use Mines ecu`s and have never repeat never lost an engine in 14 years as a consequence of running up to 1 bar of boost as I usually set it to be a maximum of that on cold ambient temperature and lower when higher ambient temperature, this why it is VITAL to do the whole set up so the engine is checked and checked again after the new map and boost settings are done, this is why selling "chips" to general public through the post is dangerous and potentially can cause issues with a badly set up engine, making random comments like "that`s brave" is counter productive to the membership who many are running just that set up from the many outlets that have done it over the years, you have been making some good progress with your mapping skills that has earned you some kudos which is cool but you need to address the whole picture when making statements or arguments for and against boost levels, mapping style, and set up. A certain tuner has a simple way of making money 10+ years ago and that was to turn the boost up and turn the base timing down, nothing more than that, horrendously stupid, a simple change of ownership and the new owner checks the timing and thinks oh retarded better move that back.........boom! so its not quite as simple as "thats brave"

 

When you have done 14+ years on just zeds with no lost engines let me know always happy to listen to experience.

Here we go. I have more experience in mapping than yourself I believe. You sell JWT chips, you don't map cars. I sell chips too. They are my own. I could mention a few cars that have needed chips removing that have been dumping a ridiculous amount of fuel down the bores, but hey ho....

 

Anyway, I wasn't even having a dig, nothing was aimed at you in the slightest. If you have an issue with something I have written, try calling me before the usual tirade. It's the fact someone's answer was "1 bar" without fully understanding the difference between a Mine's ECU and a map suitable for UK fuels. I know you don't use Mine's ECUs, IF you did and set them up at 1 bar, then... that's brave. Simple. The only point worth making is that there is no safe answer to the OP's question when you look at his list of modifications. I don't need to address anything that you mention on this particular thread. If OP runs more boost than he is now on that set up, with pump fuel, it is NOT safe.

 

Please don't patronise me. When you have mapped as many cars as I have in the last 10 years, let me know as I'm always happy to listen to experience.

 

Noel.

I agree fully

 

 

You sell JWT chips, you don't map cars.

Correct in part, what I do and have done successfully for a long time is a service and that`s what your digging at not the chip not the mapping "the service"

 

I sell chips too.

 

Yes you do and for a long long time on ebay

feel free no secrets here

Way too complicated, a simple exchange that`s all that this is

 

 

I know you don't use Mine's ECUs, IF you did and set them up at 1 bar, then... that's brave.

 

But I don`t anyhow so that`s semantics

 

 

Please don't patronise me.

 

I was not but sometimes your one liners can be potentially to the less tech guys and girls here ( my view)

 

Noel.

 

 

To close, Noel you have by in far the most active mapping tech knowledge of anyone on the forum at this time and that`s cool kudo`s for you as I said before but there is a much bigger picture than just the map or just the chip that was my point.

 

Jeff TT

 

 

PS: I apologise to the op for taking the thread of topic slightly back to the original question now hopefully

back to the playground

Jeff and Noel - why don't you both team up to offer the ultimate in Zed tuning?

 

Mind you - the banter is interesting :)

Didnt mean to cause a fuss. I gather the mines ecu is set up for **** Jap fuel and therefore an AFR is essential before any boost increase. TBH by the time I have paid for a rolling road session to do this I may aswell just have one hit at it properly and get the car mapped properly.

Jeff, just read what was written. For the last time, there was no dig at you or any service you provide. I'm not having you say I'm patronising any members, or being unconstructive with the posts I make, thanks. I try & give as much help & info as possible in the areas I feel I am best suited to. Hence why I don't post about suspension, bodykits, ICE etc. I know enough, but there are people that know far more.

 

Items I sell for other marques have nothing to do with anything, the majority of the chips I sell are for naturally aspirated motronic-equipped vehicles. This is the second time you've brought it up, I suggest you leave it. Any service you offer has nothing to do with me. There's no point going into details about anything because it'll end up locked (http://www.300zx.co.uk/forums/showthread.php?177500-Jeff-at-zedworld) and besides, it's just not the place.

 

With regards to the "bigger picture", anyone that has had their car mapped by me will hopefully testify to how thorough I am and the amount of detail I go into if the person is interested. No idea what the "kudos" remark is about, I increase my Kudos Points by pushing the boundaries of stock systems, not from mapping people's cars. The "bigger picture" as far as setting up a turbocharged car consists of AFR, knock limits, heat-soak, transient response, safety margins, throttle response, off-boost performance, spark plug type, mechanical limits of clutch, turbos, engine internals etc, owner expectation, previous bodges, current bodges, future plans and so on. These are some of the variables I consider when mapping a car and advising on builds with people.

 

So yes, in future if you think I actually need to have a dig at any service you provide, just take a step back and think for a minute. I really don't need to put down other people's work and our services are very different :thumbup1:

 

My comment was aimed at anyone thinking that running 1 bar is a sensible option on a Mine's ECU. It's brave to do :wack:

 

Dannyfiveforty: It's not the AFR, JDM maps are usually rich. It's the advanced timing in the transitional & high load areas that can cause an issue with knock.

Hahaha, I reckon we'd spend more time hurling abuse & spanners at each other than working on Zeds :slap:

 

I'm already teamed up with PowerZed & Automodz :cool3:

Ok guys we have two great traders here with a lot of experience and our members love so dont fall out on the public forum just help out Danny the best way you can. We respect you both and you should have respect for each other.

Good point gary!

Sorry, I did try to lighten the tone :)
