@a91what can you look at this data log and see why my overboost is kicking in again? i got everything looking GREAT on 8% DUTY cyle so i was going to move the boost up a bit and start adding fuel. well now its cutting fuel. i did get it on a data log tho.

8% was only 7PSI if that matters i only went to 9%

 

[a91what]

looks like 9% netted you 170KPA at 335s in the datalog, you overboost is set to 170... so it did its job and kicked in. If you have any smoothing on the load field remove it and likely you will see where you achieved the almost 12PSI at 4100 rpm when overboost kicked in....

 

[Anti_Hero0932]

I probably need to change to the small spring and creep up to 10 then... I’d like to run 12 when it’s all said and done but I don’t want to Lean it out getting it there

 

[Anti_Hero0932]

So to find KPA the calculation is

(boost psi +14.5)/0.145

correct?

 

[a91what]

Should be 14.7 = atmosphere
But yes 1kpa =.145psi
170kpa should be 10psi roughly.

Don't forget, the baro is calculated in as well.

 

[Anti_Hero0932]

ok thats close to what im getting. 168 is what i was figuring. my over bost is set to 170 so maybe its just hitting 10 psi. so 12 psi should be roughly 196kpa

 

[a91what]

No I used the boost psi field in MLV it did in fact see 12psi for a split second as overboost turned on.

 

[Anti_Hero0932]

hmmm.... alright. i havent got a chance too look at the data log again. i think the field for the protection is set to 170 tho. ill have to look im at work at the moment.

 

[a91what]

Your protection field is set to 170, but that's almost 10.7 psi. If you split hairs.

 

[Anti_Hero0932]

im gonna switch to the smaller spring tonight and start this over again. 8%-9% must be to big of a change on the tight of a spring. so if im wanting to net 12psi should i set my boost protection to 14psi when its all said an done? that would be 196ish ?

 

[a91what]

203kpa is 15psi so 196 would be about 14.

 

[Anti_Hero0932]

alright.... i mean typically you want you over boot a few psi over what your going for right? for example if your going for 6PSI set it at like 8? 10 psi set it at 12?

 

[a91what]

Yes, the idea is to stop runaway boost in case of failure of the wastegate or boost controller

 

[Anti_Hero0932]

@a91what hoping this takes care of my problem.....

i put the vac line to the bottom of the wastegate only and drove it a lot this weekend. no matter how much duty % i put in the table it was 6PSI

 

[a91what]

thats odd..

I just went and re-read how this is all setup.. some issues..

the output you are using -tachout- is only rated at .3 amps, that is not enough to drive the EBC. It is enough to drive a relay though...
the fan output is on ALED that can PWM and carry 3amps, suitable for the EBC..

you now have two options
1. swap the ALED[labled fan] and the TACH wires...
2. build a tansistor circuit to drive the EBC from the TACH output. =PITA

if it were me i would swap the wires, dont forget to swap the port settings on the outputs..
-make sure the TACH output turns the fan on correctly using the [TEST I/O] in the canbus/test modes tab

I sincerely apologize for not catching this sooner... I hope the Tach out circuit is not damaged.

 

[Anti_Hero0932]

LOL CRAP!


hey thats fine. as long as we can get it fixed its all good.

btw i may post a pic later of a wire they sent with the kit i got . it looks like a pin you can add for another output but im not sure where to pin it.


ill change those wires tonight its supposed to rain all week here tho so ill have to test it when it drys up.

 

[Anti_Hero0932]

wo0o00o0ot finally making some head way. car feels 100% better.

 

[Anti_Hero0932]

Question..... have you seen people use the Dell Venue 8 for tuner studios? looks like some people use them as a dash.... didnt know if there was any pros or cons to this...

 

[stanglx2002]

If you are planning on putting it in your instrument cluster it most likely won't fit as there isnt enough space height wise.

 

[Anti_Hero0932]

hmmmm..... alright yeah i thought that would be pretty sweet to have all my info right there visible....
