plugged data scan in is this all ok?

as title says thought i would plug it in as i havent used in a while ... only 1 code and that was temp sensor will order another sometime soon heres the data scan photo is the timing ok ? it seems to go from 16 18 20 no less no more



thanks

sam

Timing should be between 18 & 20 degrees

thanks gaz thats what i thought will have a look tomos do you know if the rest is oki? throttle sensor is set right ?

Yeh throttle position is fine... Aslong as its 0.50 or below its ok Mines at 0.10 haha. ... but 0.50 idealy, so your close

i bought it from ed at fusion the cable and then you buy the package off the internet for 70 quid i think cant remeber bought it over 4 years ago ... but once u paid for it u can download it 5 times with five acces codes then you have to pay again (so basicly if you have a shity laptop or computer that likes pissing about dont use it lol buy something that will keep nds on it )

Ok cheers bud

So its not just a program you install & you've got it for life? You have to renew it? Thought it only tells you what the car is doing like in you above pic? I don't understand why you have to renew?

yea you got it for life well kind of as long as ur pc or laptop doesnt fook up lol which i havent had alot of success with when it comes to that the first 3 laptops died cheap nasty ebay things .. 4 time on my ex fiancé laptop which she took with her when she left in november now im on my last copy of it on a computer so not easy can only look at eveything on tickover unless i get a long extension lead that will go round town lol and put the computer in the car with me haha
so really you dont have to renew it ever... and it can read error codes map set up and other stuff i dont know how to use...

Ahh cool, ill have to get it then

Spark plug Spike is good with this as you know gaz

Yeh I know mate... Just need to look at getting it myself

Deffo just ment when you do he can show you things on it he learnt me alot with it.

Yeh deffo, Don't understand how Spark plug spike is good with this side of things but cant fit a spark plug?

Gaz you've got 3 options on cables and the free software that comes with them is very good. I would say ECUtalk software is the best free one because you can data log. Nissan datascan is $52aus which is about £35 and you can get a new license easy when you get a new computer, things have changed since Sam bought his... You get a few extra functions with the paid version that are good but not so much a 'day to day' benefit, essentially there's a few options that you can fool your ECU with for diagnosis reasons.

Options
1) 14pin serial consult with USB adaptor, £20ish.

examples are this:

plus this:
http://www.ebay.co.uk/itm/USB-2-0-TO-SERIAL-ADAPTOR-/141433766102

i have both the above and can confirm they work fine. I got a 1m serial cable extension so my laptop can sit on the passenger seat no problem, the cable that comes with it is not quite long enough. Like this but 5m might be a bit long but you get the gist..

http://www.ebay.co.uk/itm/5m-Long-9-Pin-Serial-RS232-Com-Male-to-Female-Lead-Extension-Extender-M-F-Cable-/230773031389

(do NOT get a 'Null Modem' cable extension the pin layout is different.)

2) 14 pin thingy with built in USB adaptor like this:
http://www.ebay.co.uk/itm/OBD-14-Pins-USB-Diagnostics-Scan-Tool-Interface-1989-2000-DDL-For-Nissan-Consult-/161373715332

i have no experience of this type but should be as good as option 1. Note the little CD you get with all these cables has some free software on it like ecutalk, datascan demo which are the best free ones.

3) ECUtalk cable is neater as in it fits under the fuse box cover and can be left in permanently. has USB thingy built in but at £50+ is more than double the above.

Good luck!

Cheers for the write up mreguest much appreciated

Now now Gaz don't start picking on me or I won't help you out in the future

Anyway back on topic, these are my readings via Nistune (free to use) consult cable (£15 off ebay) and my home made AFR cable that costs penny's to make.

Sam, these are the readings in 3rd gear at 7000rpm, hopefully you can cross reference them with yours to see if they are similar?

What operating system are people I people using? With windows 7 as soon as it recognises the ecu my computer restarts itself.

i'm using windows XP, nissan data scan (plus all the free ones work) and the cheap ebay cable with usb to serial converter.

what software and cable are you using? have you checked with the manufacturers of your cable and software to see if they are supposed to work on Windows 7? (I know my USB to serial adaptor would not work on Win7 but you can buy ones that will do...)

All who's reading this thread should read this page many times over: http://www.plmsdevelopments.com/sr_setup_tips.shtml#7.z32_afm

note the GTIR timing is 20 BTDC, NOT 15 as per S13!!! and make sure the TPS is 0.5V when engine not running but ignition on. clear the ecu self learn first before doing the timing stuff, sort it out and then go for a drive!

i've just set up my car today using timing strobe gun and datascan and all is much better! I've not done it for ages and thought it was about time... I found things were not as they should be. The timing was way out so now it's fixed and the idle is lower, engine running smoother etc... i'll chuck it on the rollers soon to compare it to a few months ago and report back, probably next weekend.

Good luck!

Timing should be 20 when in fixed timing mode on the laptop. In fixed timing mode you set the pulley to 20 BTDC with the strobe so then the ECU is 20 and the pulley is 20. Then when you're back in normal engine running mode what ever the datascan says the pulley should be the same with the strobe. So at idle you do not see 20 it can fluctuate all over the place to compensate for a whole bunch of engine parameters. It is not uncommon to see 10BTDC at true idle. As per link above check that the ECU is actually seeing "TPS Closed". It monitors the TPS position and when it's in a certain range (normally 0.35 to 0.65V) it assumes the throttle is closed. This triggers a flag in the ECU which makes it go into idle mode, on datascan that's the "closed TPS on/off red and green lights".

it is very important to set your TPS to 0.5V. The ECU can compensate for errors between 0.35V to 6V, so set it to 0.5V and then you have some +/- tolerance.

Gaz 0.1V is wrong. Your car might run ok because the ecu has compensated by doing changes to a whole bunch of other stuff. If you were to clear the self learn (i.e. reset ECU back to factory values) it would freak out. Has your car been mapped? maybe this is why 0.1V is ok on your car...

Ebay cable (big grey one) and a proper serial converter that is win7 compatible, it's probably the consult cable that isn't, I had a sneaking suspicion I would have to dig out an xp disc.

Cheers for the confirmation that it all works on xp.

Timing on my r as I have a uk car with uk ecu is the timing still 20 deg or more or less ? I just thought about it just now for some strange reason thanks
