Still having problems with blitz ecu

[ASHep82]

Hi guys I recently bought a blitz ecu for my Glanza at 1st I just plugged it in and started driving.it wasn't running good at all so I plugged it out for a couple of minutes and plugged it back in again and let it idle for about 45 minutes and drove easy for about 100 miles,after this i took it on the motorway and drove the car pretty hard and it was fine but took it out today and at about 5k revs the car judders feels a bit like a misfire then it runs fine again it doesn't do this in 1st gear and sometimes it doesn't do it all.
getting really pissed off now.Iv recently changed the spark plugs with some basic ngk ones and got some ultra leads aswell my other mods are cat back exhaust and bypassed the boost selonid.it's currently boosting at 0.7 but does creep up to 0.8 and when its cold it creeps upto 0.9

Please help guys getting really frustrated

Its possibly your plug leads not fit for the job

 

[ASHep82]

The leads are good quality ones theyr ultra ones in Red.could be the spark plugs tho as they're cheap ngk ones.what spark plugs would you recommend?my friend was telling me to get some spitfire or something like that.

 

[ASHep82]

also guys could the timing be out?and the misfiring feels more like when I was hitting fuel cut and it happens at about 5k revs and then after 5k revs it feels fine again

has the timing ever been moved as i had a jap ecu none of the fancy makes but to get that fine tuned had to alter the timeing advance between 1 and 10 degrees i no that is not the case with the blitz but like you say if it has been moved on dizzy could be at wrong angle, but first i would def be dropping some iridiums in there with a heat range of 7 for future mods it is quite easy to check the timing with a gun and you can get a lead tester for around £10 for motor factors that will show if there any damage in lead, i had a set of magnacores and after 7 month i developed a problem and replaced everything but them as didnt think it could be them but after a basic meg test there was a bad resistance in one of my leads and that was the problem.

 

[ASHep82]

Haven't touched the timing mate.think I'll start with changing the plugs again to some iridium ones.thanks for the help guys.any more suggestions guys?

stock ecu works fine?

 

[Vincent-ep91]

i would change the leads, or even get a loan of a set from a friend and try them out.
I have experienced similar problems and it was down to shitty ultra leads.

Bet it's running to rich not much u can do there unless u wanta buy a safc u should have bought a good ecu in the first place I've been saying this for years y buy a ecu that u can't tune ...... O that's rite they tune as ur driving lol or not

that is all well and good saying that mate but in some circumstances these ecus are better than getting some pikey to map the car badly. i cant map but have done a better job than where i took it and got ripped off.

i have a jam ecu and have used it on 2 different cars and am more than happy with it.

people think these ecus are magic or something

there was 3 different types of blitz access for the 4efte! each one mapped for a corresponding blitz turbo so it depends on the ecu you have. so maybe you have top level ecu there and not running the boost its mapped for and its running rich as above its just a guess

you cant just wack one of these is and expect it to work these were sold as part of a kit not sold separate so if your setup is different than what its mapped for then you will have problems. it does have a self learning to a degree but its only between the parameters its mapped for. the majority of these ecus work because alot were mapped for the hybrid turbo running the 1-1.2 bar range and thats more than likely what you are running. but you get the rare one thats mapped for higher boost and you will run into troubles

chris is spot on there and a safc will be needed to fine tune it if indeed that is the case. think about it lads your putting in a ecu that no one knows what its mapped for you can just expect it to work fine cause thats madness, remember these were mapped on 100ron aswell

i would look over the basics first lad plugs, leads ect and see if you can solve the problem if not then get in a check the afrs you are running and if its not right then you can get a safc ect to fine tune your setup

Sheldon the stock ecu was fine but I didn't have the hi lo selonoid bypassed.when I did bypass it with the standard ecu I was hitting fuel cut so couldn't really tell now with the boost selonoid bypassed and blitz ecu it's boosting at 0.7 the car does feel alot quicker than before.

Iv recently changed the spark plugs with some basic ngk ones and got some ultra leads aswel

First thing I would do is check the leads are clipped on securely, even pulling them back off both at the plug end and the distributor and also at the coil, spraying some WD40 or something similar into the connections and refitting it all may prove to be beneficial. If that doesn't make any difference pull the plugs back out and check their condition, if your not sure whether they look OK or not take a photo of them and post it up. Make a note of the cylinder each plug came out of. If the plugs do look OK then I'd suggest refitting the old leads and see if the problem persists.

On the ecu it says k1-200v written with permanent marker.I had a blitz ecu on my previous Glanza with the same writing on it that use to run fine the spec on the other Glanza was the same but had 60k miles and the current Glanza has 85k miles.I'll try with the plugs.also it doesnt misfire all the time sometimes it's running fine and then sometimes it misses it just does it at about 5k rpm and it's just the one misfire when I say misfire i could be wrong feels a bit like fuel cut too but obviously it can't be fuel cut

 

[markostarletturbo]

Like said above check leads/plugs if you can borrow some? also get afr checked i have blitz access used it with no issues and more than happy with it

 

[weeJohn]

Do you have a non linear RRFPR fitted, non stock injectors or is your fuel pressure higher than normal?

I would fit the stock FPR on the car, change the fuel filter and try again. Also check the pins on the ecu have not been bent or damaged in any way and that no wires have been pulled out of the loom plugs.

Why is it when ever i hear of problems with theses type of ecus its always with blitz access is it just me? I have mines and runs spot on and i have never heard anyone complain about jam and the likes.

 

[ASHep82]

The fpr is a stock one and the fuel pump is stock too.Iv got a set of spare which I'll try and I'll check if the pins are bent too as soon as I finish work

almost every brand has ones that are much off.. know of one mines that was running to much timing and ended up breaking 2 engines

What way have you bypassed the boost solenoid?
