Hey everyone,

To start with I have a 1992 GTR. I have a tps (21 flashes on ets) code fault, light on dash only comes on on first start. If I shut off car and restart no code.

Problem started after I took my car into a performance shop in Vancouver BC for a single turbo conv. , ABS delete, and performance battery.

I have tried this:

1: brand new tps - still problem

2: tried another ets controller unit - still problem

3: tested wired at ets unit 47 and 48 and got .4V

4: set my open throttle with laptop on tps to .5V open throttle

One thing that bothers me is my tiny lithium battery (LFX36L3-BS12) (http://shoraipower.com/lfx36l3-bs12-p130) they put in for maybe on first start and charging all electronics and cranking engine voltage drops to a level that will trip tps V code?

Anyone have any thoughts?

So with the ABS gone I get code 8 and 9 but with what I ascertain this will not effect AWD?!

And then the code 21 on top of these.

Thanks

Also forgot to mention I got a haltech plat pro ecu... there is tps inputs and a filter. Is there a output setting for the signal to the attesa ets? I set the input filter to 0 and have set open throttle from .38 to .5Volts

Nice copy and paste response from Matt at Haltech to an over 7 year old post there mate. The OP wasn't using a Haltech Elite either, he said a Haltech Platinum Pro so it's irrelevant to him.

From the Haltech forum:

I will give you some credit for bringing this up though, as it does need to be changed to avoid getting a random TPS ATTESA fault on the 32 and 33 GTR with a Haltech Elite 2000 / 2500. Most people probably don't know about this as to this day it is still incorrect in the GTR base maps. Was happening on both of our Elite 32s.

A bit like the Elite speed signal set at 2450 pulses per km in the GTR base map - needs to be 1225 or you speed will be showing half of what it should be at the ECU.

Haltech really should correct this in the base map for the GTR as I don't think this is common knowledge and why would it be - you'd expect these things to be correct in a GTR specific base map.

    • Man that dinner was such a long time ago....2010! I would only replace the rubber coolant lines with silicone these days; cheap, readily available and will last for ever. You will need new hose clamps though eg https://justjap.com/products/cooling-pro-silicone-engine-heater-hose-set-black-nissan-r32-gtr-rb26dett
    • I wouldn't look too hard at what they did with the R32 GTR in endurance racing in Australia... Lots of things weren't actually available from the factory in the way those cars ran them... Japan also followed what Fred Gibson was doing here with some of there endurance cars in Japan... Australia is also the reason for things like the Brembo brakes, and the change in the gearbox... And quite a few other tricks they used to pull. There's a few other SAU peeps still on these forums that will have heard the stories direct from Alan Heaphy, Fred Gibson, and Jim Richards when we were lucky enough to have a great dinner with them
    • For all the talk of "these parts are junk" I generally recommend OEM because it's really not as bad as claimed. I have never seen or heard of a case like the N63 where the oil returns completely clog with coked oil for example in ~10 years or less. Would it be nice if it were a straighter path? I guess, but most modern cars use a scavenge pump instead of a pure gravity return. Also the factory lines that would be relatively simple to convert to braided are generally speaking hardlines from the factory. I would consider braided line to be a regression, not an improvement. It's also been engineered such that all the hardlines have appropriate strain relief where needed. There's absolutely room for improvement, for example the HKS advantage heritage intake piping shows just how much can be done to make the turbos fight each other less in OEM twin turbo configuration and reduce compressor surge but it's rarely a simple/straightforward process. I recommend looking at what the group A/N1 cars did, generally speaking the changes they made were necessary and proven in endurance racing.
    • Yes, multi relays needed, and possibly a diode. I'm not actually going to think about it though.
