Gotech Pro X nearly melted my engine

if we get an ECU returned to us at Jamsport we run some initial tests, repair if needed, then give it a quick bench test before testing the ECU on a car. Nearly all ECU's returned either have a blown driver caused by power being fed down the wrong wire or there is no fault with the ECU when we run it on a test car, thus indicating a bad installation by who ever fitted the system to the car. Another issue is people knowing how to install the loom properly & adjust the noise filter within the ECU to stop interferance.

We had issues with my brothers, not the kit directly more the seller who has still not given us any straight answers to questions we've had regarding the ALS. They only seem interested in trying to sell us all ther new shiny stuff (as it was apparently the only way to achieve the sort of power level we were chasing), once the guy realised we hadn't come down in the last shower and we did actually know a bit about what we were building he turned tail and we've not heard a sniff since which has left us having to try and find the asnwers elsewhere

Fair enough, but if, and its a big if as its all via the interweb, there is a common problem seeming to appear from a few people with units that seem to have been fitted for a while then it would be nice to know if there is an inherant problem or not. A lot of ifs,buts and seems
As always its very easy to find negative reports about anything, as people are always ready to moan but not so easy to find good reports.
Purely interested as I have a Gotech to fit this winter but could quite as easily fit a different make, especially as I'm still waitng for an email reply about dressed looms

Is there something about the Gotech Pro X that has caught out the experts? IMO it should just work.

If needed in the future....
I would be happy to bench test an ecu on my engine simulator and extensive logging system.
I developed this system for a major engine diagnostics tool manufacturer and it is well proven.
I have no axe to grind with Gotech and am fully independant of any tuner !
As an ecu designer, I am best placed to identify design flaws if this is the case wheras "tuners" are not !

That would worry me. An experienced tuner fitted my ECU and I trust his knowledge and experience. If there was something about the ECU that caused problems because it required technical knowledge beyond what an experienced tuner has, then that is a problem.
Is there something about the Gotech Pro X that has caught out the experts? IMO it should just work.

A lead to a cranksensor that was running close to a plug lead, or coil could interfere with the signal to the ECU, thus causing a misfire.

we have never seen the ecu back with us to test (from your supplier) also we wouldn't offer a replacement unit unless the ECU was beyond repair and we had tested the suspect unit & confirmed that any damage wasn't caused by a 3rd party, installation issue or water damage.

Matt,
you can now appeal your infraction in this new room.
Here... https://passionford.com/forum/infrac...on-queries-62/
Get in quick mate as I feel its gonna be a busy place in the future as it would seem the level of moderation has changed and no announcment has been made !
A bit sneeky really !

As you said, you just answered a question. Hardly actively trading, in fact not even discreetly trading. Simply answering a question.
You should have had a PM explaining the infraction, and as Simon says above, get on and appeal it if you feel it is unfair.
Bit of common sense / discretion needed on this "infraction" surely Mods?

Cheers chaps, i got a pm about company details in my sig & a pm about the infraction, to be fair i didn't realise our trade membership was up, our account lady is away so i can't ask her about it either. I just found it very petty, in answering a question i was in the wrong....... I understand the site has to modded and i agree with it to keep things in hand, but theres moderating and theres being petty

^ If you got told off for a breach caused by a genuine lapse in subscription fees, that experience would not motivate me to renew and I would be pretty annoyed tbh.
Having said that. When you post it is clearly apparent that the grey/silver TRADER badge is missing. That would alert me that something was awye and to investigate.

Had a chat today...
///warning! Person lacking technical knowledge is about to impart technical knowledge///
1. My knowledgable and experienced tuner suggests that the noise filter, which is designed to look at the incoming square wave and cancel out any additional noise caused by vibrations and other electrical fluctuations from the car's electrical system is not very good on the Gotech. He feels that it does cancel some noise but also tends to ocasionally cancel out the crank sensor input signal which causes the ECU to behave erratically.
2. Same tuner has had plenty problems in the past on the slightly lesser specced MFI Pro. This ECU he thinks has now been withdrawn from sale because of similar problems.
3. He isn't sure if the random spark trigger signals were caused by hardware or software but believes that problem number 1 coupled with poor quality design caused the problem.
Conclusion: He said he'd never fit one or deal with them again.

Jamsport and Gotech still have the Pro X on there site, so I don't think it has been withdrawn.
As for the filtering, when I fit an ECU, all injector, TPS etc are kept well away from leads, the CPS is always shielded, so thats half the battle. If the noise filter is not up to the job, why would it only affect 1 ecu in so many sold, we run 3 of them at the moment, and never a problem. The guy that does all my mapping has sold a lot of them and he has never encountered a problem. Has the ECU been returned to Jamsport or gotech for there opinion.

I don't know if the ECU has been returned. It's no longer on my car. I assume it'll go from Enhanced Performance to JamSport.

No disrespect but a "tuner" is not the right person to confirm or deny such a technical response especially when he refers to the crank signal as a square wave when it is actually no such thing !!!
It does sound like the diagnosis is correct to me given the situations of the reported failures but bad and/or incorrect installation can cause the exact same issues. !

I thought the crank and dis signal on the YB was a square wave pattern, but you may be able to enlighten me.
You are correct in saying that this kind of problem is usually associated with bad and/or incorrect installation

In a simple terms its a positive rounded upside down V shaped pulse closely followed by a negative pulse of similar amplitude.... (Sine wave ...ish)
Not square in the slightest. !
You get the positive pulse as the crank lug moves past the sensor and the negative part as it moves off the lug.
It is a voltage measurement of inductive reactivity in relation to speed and time.

Danny,
I am not saying it is one thing or the other as I have not seen the setup myself.
It could be anything, even a faulty sensor or missalignement on the crank etc...
Time/heat and movement can affect any of or all components on a car including the wiring !
The only way to check for sure is with a dual trace ocislloscope....
One trace on the sensor output as it enters the loom and the other trace inside the ecu after the digital conditioning circuits... !!

I agree with you Danny. Luke seems experienced in car electrics and has done plenty of looms and ECU installs. And as you say, my car was running fine for a while without issues.
I'm keen to know what a tuner could do to wrongly install an ECU? Surely the loom and earth need to be OK. It's not that technical is it?
My car now has a Link ECU. I hope it's a new loom on the car as Luke charged me for a new loom
ECU Monitor Enthusiast you say "The only way to check for sure is with a dual trace ocislloscope...." but I disagree. Luke used a signal generator through the ECU with no loom connected and the ECU started generating random spark signals. This is enough to determine that the problem is with the ECU as the ECU was tested in isolation.
