boosting ar 0.5 insread of a bar

[VR4Kaos]

as some of you may know i bought an ecu off nutter john and kinkyafro which was allowing me to boost up to a bar.
my car started stalling (again) so went searching for boost leaks found 3 or 4 replaced hoses then found another on my boost selenoid upon removing this hose i snapped the nipple that the hose connects to i heard you can bypass this selenoid so tryed this to no avail still stalled and ran like a dog so i then got a replacment maf which has cured the stalling but still runs poo so then got me a replacement selenoid off nickmann (thankyou nickmann) i relaced this and couldent boost passed 0.5 bar and had no bollox so thought it was a failed selenoid but thought when i buy the blitz ebc off Gowf its duel selenoid so will be able to elimante this selenoid. Well i can boost upto 1.2 bar with this but when switched off cant get me passed 0.5 i hear what nj said bout running on wastgate ect but how come this happed before the ebc was insalled with a replacement selenoid.
summery
replaced leads kv8
replaced plugs irroedum
flued change
remapped ecu peak boost 1 bar
blitz ebc
GAIN = absalutly nuthing timed 0-60 when first bought the car bout 6 seconds and now it is sitll 6 seconds 8 seconds with ebc turned off
i know nowt but can feel everything

Wasnt this answered before mate....If you dont have a standard boost solenoid anymore how can the ECU tell it to run 1bar of pressure?
What happened before dont worry, it holds pressure with the EBC so just leae it turned on

Leave the EBC turned on at a bar all the time and you will be fine

[VR4Kaos]

it was but nah im not happy with that answer mate it aint right trust me mate ive drove faster mini metros honestly

[mattnz]

0.5 bar sounds about right with EBC turned off? Or am I missing something?

[VR4Kaos]

yeah mate ive got a remapped ecu boosts upto a bar standard well did do !

[AlanDITD]

can the ecu be checked that it hasnt gone back to the old settings? if thats possible

[VR4Kaos]

i would need nutter john to cheak that one out mate

[Wodjno]

The ECU can't go back to it's old settings !
If the Old solenoid was fooked and also the new 1.. Even with a remapped ECU, you won't see more than wastegate pressure(0.4-0.5bar) with a non working solenoid..
With an EBC installed, it has total control over boost. The Boost Map in the remapped ECU is useless as the ECU would need the OE solenoid to make adjustments upto what the remapped ECU is set at..
It's a possibility that the replacement solenoid is a good working 1 ! And with all the mish mash of pipes you had taken off n on n off n on again. You didn't get it installed properly so it would not work and you would only achieve wastegate pressure.

You say your getting 0-60mph's of 6-8 seconds with the EBC turned off ! And it's slower than when u 1st got the car ? well it would be as with the EBC turned off u are getting leass boost than if the standard solenoid was still in the loop(which it isn't as you have isolated it by fitting the EBC) And i'll say it 1 more time.. With the EBC fitted the Remapped ECU for 1 Bar is useless for Boost control. It has no affect on Boost control whatsoever.

Hope this helps Karl ?

But theres still nothing in what i have typed that hasn't been said already !

I am sure it is down to you lack of understanding on how all the Gubbins works..

Cheers

I must be thick because I can't see what your problem is. With the EBC turned off ( why turn it off anyway) your boost is around .5 bar which is what it should be and when you turn it on (to position 4 presumably) it is just over 1 bar which is what it should be. I take itwhen you turn it to positions 1, 2, and 3there are progressive increases. If you are running at 1 bar even in this heat 0-60 should be below 6 secs

Karl, join me in chat when you've got 5 mins, I'll try and get a clearer picture of what's happening and report back here.

basicly my car was faster with more touque with stock ecu and an mbc feel like ive wasted over a £600 for nowt

The car will feel quicker of the line With a MBC than with your EBC. But that is initial surge. Thatd because a MBC had no control of hot fast the boost rises. Stock solenoid and EBC solenoid will bring the boost in more progressive. this may seem slower, but the EBC will maintain a higher chevron id boost than the MBC. Also it with stop boost spiked, which can also induce knock which is damaging it engine little by little. You should be able to adjust the verocity of hoe the boost comes in by adjusting the Gain. But at the risk of dooming and damaging your engine.
If you had in gear acceleration figures (30-70, 50-90, 30-130) for EBC and mbc u would see the EBC is making it car overall faster and safer..

As i said on saturday Karl, when we were setting it up the ambient temp was around 28C. This will have a huge impact compared to when you had it before in winter when it was around 28C less!

The one thing that we need to look at is whether it is knocking. If it is then it could be pulling timing and therefore reducing your power. However if you run it on setting 3 and it feels slower than setting 4 then this will not be the case. Before anyone goes on about correct knock detection, im fully aware this is not a true way of detecting it and det cans should really be used but its something that i forgot to bring with me when driving up the road. Other than that, your boost is at a relatively sensible level, but as glen as said the mbc would have brought the boost in quicker but in a far more spiky way, it will be holding the boost far better now with the ebc

[VR4Kaos]

how come is it then i have no excelleration improvement from stock to now

[John TheAntique]

What is your 0-60 now then?

[Nutter_John]

Ok let me try and explain , but to do this I must seperate and clairfy

The ecu you bought from us does the following things to a stock car
a) Changes the fueling of the standard map
b) Changes the fuel cut zones of the standard map
c) Changes the speed cut
d) Changes the stock boost levels to around 1.1 bar

Forgetting all the issues you had with boost control you now have a boost controller so the ecu can only do the following things for you

a) Changes the fueling of the standard map
b) Changes the fuel cut zones of the standard map
c) Changes the speed cut

As part of the install of the EBC you remove the abillity of the ecu to control boost .

If you want Karl I am more than willing to send back your old ecu and refund the money for the reflashed ecu as you seem to not be happy with the features it gives you

As gareth says.. Your car will die in this heat.. Especially with a standard Intercooler..

I ran sub 5sec 0-60's on a daily basis with my 1st VR4.. So did Enigma

We went down to TRAX at Silverstone and it was around 30 degrees. It was as though we had lost a Turbo There just wasn't any kick in the back that we was used to.. And if i recall my best was a 5.9 and Enigma's was around 5.6sec

All due to the heat..

hiya john mate sorry if it sounds like im been offish im happy with the ecu you supplyed but feel as tho ive done some thing wrong (broke something ect)
the ecu gave me simaler rr rusults as i rolled in with, with the mbc which was w@nkard and unsafe my car not been right since selenoid issue altho this may not be the issue i presume so as i snapped the nipple so then tryed to bypass it to no avail then rehosed the replacment one wrong wether this has broke somthing or not i don't know but what im failing to get everyone to understand is this is coinstadently the wastegate pressure is the same boost pressure as before the ebc install

[Wodjno]

but what im failing to get everyone to understand is this is coinstadently the wastegate pressure is the same boost pressure as before the ebc install

Whether you got an EBC, MBC, No BC, Vipec, EMU, Map2 etc etc etc ..

Wastegate Boost Pressure wil not change

The only way you can alter the Wastegate pressure is to either change it for a stronger wastegate on modify the existing 1. !

[VR4Kaos]

So is the case of zero 0 -60 times not increasing after an ecu remap and ebc install right
